Amstrad CP/M Plus character set

The Amstrad CP/M Plus character set (alternatively known as PCW character set or ZX Spectrum +3 character set) refers to a group of 8-bit character sets introduced by Amstrad/Locomotive Software for use in conjunction with their adaptation of Digital Research's CP/M Plus^[1] on various Amstrad CPC / Schneider CPC and Amstrad PCW / Schneider Joyce machines.^[2][3] The character set was also utilized on the Amstrad ZX Spectrum +3 since 1987.^[1]

At least on the ZX Spectrum +3 it existed in eight language-specific variants (based on ISO/IEC 646) depending on the selected locale of the system, with language 0 being the default for "US".^[4]

Another slight variant of the character set was used by LocoScript.^[5][6]

Notes

1. Code point 0x30 is intended for zero with a slash, 0x7F for zero without a slash. Both can be expressed as Unicode character U+0030, but of course if both are converted to the same code point the conversion is non-reversible.

[…] The selection of characters made available on computers sold in different countries are subject to national variations. As a result, CP/M has different national language versions of the screen characters. […] Immediately after […] load […] it is set up to use the US character set […] The codes CP/M uses are […] in the range 0...255 […] A handful of these codes represent different characters, depending on which national language is selected. […] All the different national language versions of CP/M are supported on the Spectrum +3 and a special utility has been incorporated into the CP/M system to allow the user to swap from one national language to another. This is the LANGUAGE utility. […] The 'standard' set of codes and characters represented by these codes is the US character set. What happens in the other language versions is that certain codes in the first half of the character set (0...127) are associated with characters that are in the second half of the US character set and vice versa. In fact a straight swap is made between the code used for the special language character, and the character it substitutes. For example, in the US character set, the code for £ is #A3: when English is selected, £ replaces # as the character with code #23 - and # replaces £ as the character with code #A3.
