{{Short description|Handheld calculator character set}}
The '''RPL character set''' is an 8-bit character set and encoding used by all [[Reverse Polish Lisp|RPL]] [[electronic calculator|calculator]]s manufactured by [[Hewlett-Packard]] as well as by several HP printers. It is sometimes referred to simply as "ECMA-94" in documentation,<ref name="HP82240B_1989">{{cite book |title=HP 82240B Infrared Printer |publisher=[[Hewlett Packard]] |date=August 1989 |edition=1 |id=HP reorder number 82240-90014 |location=Corvallis, OR, USA}}</ref> although it is in fact a [[superset]] of [[ISO/IEC 8859-1|ISO 8859-1]] / [[ECMA-94]] in terms of printable characters, and it differs from the IANA's ISO-8859-1 by using displayable characters rather than control characters in the 0x80 to 0x9F range of [[code point]]s.

In 1986,<ref name="Nelson_2010"/> the ''original'' series of RPL calculators ([[HP-28 series]]) as well as the HP&nbsp;82240A [[thermal printer]] used a [[HP 82240A character set|modified variant]] of the [[HP&nbsp;Roman-8]] character set, of which characters above 147 could not be displayed on the calculator, only be printed.<ref name="HP28S_REF"/><ref name="HP82240A_1986"/><ref name="Nungester_1988"/>
The following table shows the HP RPL character set. Each character is shown with its [[Unicode]] equivalent and its decimal code.

This changed with the introduction of the HP&nbsp;82240B printer in 1989<ref name="Nelson_2010"/> and the [[HP&nbsp;48 series]] in 1990, which came with a new character set now based on ECMA&nbsp;94&nbsp;/ ISO&nbsp;8859-1 instead of HP&nbsp;Roman-8, but with the control codes in the range 128 to 159 (0x80 to 0x9F) being replaced by additional displayable characters. Compared to ISO&nbsp;8859-1, code point 127 (0x7F) showed a medium shaded gray box like in the former HP&nbsp;Roman-8 based character set. Code points 131 (0x83) to 142 (0x8E) were also taken over from the former HP&nbsp;Roman-8 based character set. In addition to this, code point 31 (0x1F) was used for ellipsis ([[…]])<ref name="HP48G_UG"/><ref name="HP50G_AUR"/> and code points 169 (0xA9) and 174 (0xAE) showed ambiguous glyphs which could be viewed as inverse circled number [[❸]]<!-- (U+2778) --> or [[copyright symbol]] ([[©]]) and as [[❷]]<!-- (U+2777) --> or [[registered trademark]] symbol ([[®]]), respectively.<ref name="HP82240B_1989"/><ref name="HP48G_UG"/> This ''first version'' of the character set also had a [[non-breaking space]]<!-- (U+00A0) --> at position 160 (0xA0).<ref name="HP82240B_1989"/><ref name="HP48G_UG"/><ref name="Paul_2001"/>

In a ''revision'' of this character set in 1999, code point 160 (0xA0) was redefined to hold the [[euro sign]] (€)<!-- (U+20AC) --> in the [[HP 49/50 series]] (including the [[HP&nbsp;48gII]]),<ref name="HP50G_AUR"/><ref name="Paul_2001"/><ref name="Rautenberg_2004"/><ref name="Prange_2005"/> now deviating from ISO&nbsp;8859-1. Code points 169 (0xA9) and 174 (0xAE) were now clearly defined as holding the [[copyright symbol|copyright]] ([[©]]) and [[registered trademark]] ([[®]]) symbols in compliance with ISO&nbsp;8859-1, whereas the corresponding glyphs still resembled the inverse circled numbers more.<ref name="HP50G_AUR"/> The last calculator supporting this variant of the character set was the [[HP 50g]] introduced in 2006 and discontinued in 2015.

In a parallel development, the [[HP&nbsp;38G]] also used the HP&nbsp;48 series' character set internally. Starting with the [[HP&nbsp;39G]] in 2000, the superscript 3 ([[³]]) at code point 179 (0xB3) was replaced by a superscript -1 (<sup>−1</sup>) in the [[HP&nbsp;39/40 series]] (except for the [[HP&nbsp;39gII]], which started to use [[Unicode]]).<ref name="Croft_2006"/> Code point 160 (0xA0) was also changed to the [[euro sign]] (€)<!-- (U+20AC) --><ref name="Croft_2006"/> in this ''third variant'' of the character set. The last calculator supporting this variant of the character set was the [[HP 40gs]] introduced in 2006 and discontinued around 2011.

Hewlett-Packard never defined an official Unicode translation, hence several variants evolved in the community, differing in code points 31 (0x1F)<!-- U+001F, U+2026 -->, 127 (0x7F)<!-- U+007F, U+2592 -->, 128 (0x80)<!-- U+0080, U+2220, U+2221, U+221F -->, 129 (0x81)<!-- U+0081, U+0078+U+0305, U+0101, U+2327 -->, 133 (0x85)<!-- U+0085, U+03A3, U+2211 -->, 134 (0x86)<!-- U+0086, U+25BA, U+25B6 -->, 158 (0x9E)<!-- U+009E, U+25A0, U+25AC -->, 160 (0xA0)<!-- U+00A0, U+20AC -->, 169 (0xA9)<!-- U+00A9, U+2778, U+U+278C -->, 174 (0xAE)<!-- U+00AE, U+2777, U+U+278B -->, 178 (0xB3)<!-- U+00B3, U+207B+??? -->, 181 (0xB5)<!-- U+00B5, U+03BC --> and 223 (0xDF)<!-- U+00DF, U+03B2 -->.<ref name="Lehmann_2000"/><ref name="ASCII-CA_2006"/><ref name="Bettencourt_2014"/><ref name="Dreher_2012_1"/><ref name="Dreher_2012_2"/><ref name="Dreher_2013"/><ref name="newRPL"/>

The fact that the Unicode equivalent for x-bar at code point 129 (0x81) is a combination of two characters (x̅) could cause problems in translations, therefore it was suggested to use U+0101 (ā) instead.<ref name="Dreher_2012_2"/><ref name="Dreher_2013"/><ref name="newRPL"/>

Characters which cannot be reasonably transcoded should be mapped to code point 127 (0x7F), similar to what the calculators do when communicating with older printers like the HP&nbsp;82240A.<ref name="Prange_2002"/><ref name="HP50G_AUR"/>

Since the calculators allow fonts to be redefined (using <code>FONT→</code>, <code>→FONT</code>, <code>MINIFONT→</code>, <code>→MINIFONT</code>) other codepages can be emulated for as long as symbols which are available on the keyboard or are otherwise associated with specific functionality by the calculator aren't replaced by unrelated symbols.

==Code page layout==
The following table shows the HP RPL character set. Each character is shown with a potential [[Unicode]] equivalent in the tooltip. Where special [[HP TIO code]]s are defined to enter the character, they are given as well.<ref name="HP-TIO"/><ref name="Heinz_2005"/><ref name="HP48G_UG"/><ref name="HP50G_AUR"/><ref name="Finseth_2012"/> The other characters can be entered using the <code>\nnn</code> TIO code syntax with nnn being a three-digit [[decimal number]].<ref name="HP-TIO"/><ref name="HP48G_UG"/><ref name="HP50G_AUR"/><ref name="Finseth_2012"/>

==History==
* The first version of the character set as used in the [[HP 48 series]] had a [[non-breaking space]] (U+00A0) at position 160 (0xA0), whereas this was redefined in 1999 to hold the [[euro sign]] (U+20AC) in the [[HP 49/50 series]].

The RPL character set is an 8-bit character set and encoding used by most RPL calculators manufactured by Hewlett-Packard as well as by the HP 82240B thermo printer.[1][2] It is sometimes referred to simply as "ECMA-94" in documentation,[1][3] although it is for the most part a superset of ISO/IEC 8859-1 / ECMA-94 in terms of printable characters, and it differs from ISO/IEC 8859-1 by using displayable characters rather than control characters in the 0x80 to 0x9F range of code points.

Übersicht

[edit]

In 1986,[3] the original series of RPL calculators (HP-28 series) as well as the HP 82240A thermal printer used a modified variant of the HP Roman-8 character set, of which characters above 147 could not be displayed on the calculator, only be printed.[4][5][6]

This changed with the introduction of the HP 82240B printer in 1989[3] and the HP 48 series in 1990, which came with a new character set now based on ECMA 94 / ISO 8859-1 instead of HP Roman-8, but with the control codes in the range 128 to 159 (0x80 to 0x9F) being replaced by additional displayable characters. Compared to ISO 8859-1, code point 127 (0x7F) showed a medium shaded gray box like in the former HP Roman-8 based character set. Code points 131 (0x83) to 142 (0x8E) were also taken over from the former HP Roman-8 based character set. In addition to this, code point 31 (0x1F) was used for ellipsis (…)[7][8] and code points 169 (0xA9) and 174 (0xAE) showed ambiguous glyphs which could be viewed as inverse circled number ❸ or copyright symbol (©) and as ❷ or registered trademark symbol (®), respectively.[1][7] This first version of the character set also had a non-breaking space at position 160 (0xA0).[1][7][9]

Translation from HP-48 to HP-28 character set:[10]

HP translation vector

8x 0xA0 0x7F 0x7F 0x83 0x84 0x85 0x86 0x87 0x88 0x89 0x8A 0x8B 0x8C 0x8D 0x8E 0x76

Ex 0xC8 0xC4 0xC0 0xE2 0xCC 0xD4 0xD7 0xB5 0xC9 0xC5 0xC1 0xCD 0xD9 0xD5 0xD1 0xDD

In a revision of this character set in 1999, code point 160 (0xA0) was redefined to hold the euro sign (€) in the HP 49/50 series (including the HP 48gII),[8][9][11][12] now deviating from ISO 8859-1. Code points 169 (0xA9) and 174 (0xAE) were now clearly defined as holding the copyright (©) and registered trademark (®) symbols in compliance with ISO 8859-1, whereas the corresponding glyphs still resembled the inverse circled numbers more.[8] The last calculator supporting this variant of the character set was the HP 50g introduced in 2006 and discontinued in 2015.

In a parallel development, the HP 38G also used the HP 48 series' character set internally. Starting with the HP 39G in 2000, the superscript 3 (³) at code point 179 (0xB3) was replaced by a superscript -1 (−1) in the HP 39/40 series (except for the HP 39gII, which started to use Unicode).[13] Code point 160 (0xA0) was also changed to the euro sign (€)[13] in this third variant of the character set. The last calculator supporting this variant of the character set was the HP 40gs introduced in 2006 and discontinued around 2011.

Hewlett-Packard never defined an official Unicode translation, hence several variants evolved in the community, differing in code points 31 (0x1F), 127 (0x7F), 128 (0x80), 129 (0x81), 133 (0x85), 134 (0x86), 158 (0x9E), 160 (0xA0), 169 (0xA9), 174 (0xAE), 178 (0xB3), 181 (0xB5) and 223 (0xDF).[14][15][16][17][18][19][20]

The fact that the Unicode equivalent for x-bar at code point 129 (0x81) is a combination of two characters (x̅) could cause problems in translations, therefore it was suggested to use U+0101 (ā) instead.[18][19][20]

Characters which cannot be reasonably transcoded should be mapped to code point 127 (0x7F), similar to what the calculators do when communicating with older printers like the HP 82240A.[21][8]

Since the calculators allow fonts to be redefined (using FONT→, →FONT, MINIFONT→, →MINIFONT) other codepages can be emulated for as long as symbols which are available on the keyboard or are otherwise associated with specific functionality by the calculator aren't replaced by unrelated symbols.

Code page layout

[edit]

The following table shows the HP RPL character set. Each character is shown with a potential Unicode equivalent in the tooltip. Where special HP TIO codes are defined to enter the character, they are given as well.[2][22][7][8][23] The other characters can be entered using the \nnn TIO code syntax with nnn being a three-digit decimal number.[2][7][8][23]

The original hp 38g only had the function INVERSE(...) and the -1 operator was added for convenience sake in the hp 39g, released in 2000. To do this the creators had to borrow one of the existing unused characters, the 3 character, and convert it into the -1 operator. However, they forgot to change it in the CHARS view and this error has never been fixed in any of the successive models!
