craft-codepage: one table per legacy code page, for craft-rtf, craft-dxf and craft-mime (#991)
craft-rtf and craft-dxf each carried tables for DOS 437, 737, 850, 852 and 857 (and craft-rtf one for 866). They are now one set in craft-codepage, which takes craft-rtf's codepage module (Windows and Mac tables, OEM glyphs, font charsets) and craft-dxf's DOS tables. craft_rtf::codepage re-exports it unchanged; craft-dxf keeps its $DWGCODEPAGE names and Decoder and looks the DOS tables up there. Every byte of every code page either crate decodes is unchanged: the public decoders of both crates were dumped over all 256 bytes of each page (and the East Asian pairs) before and after, and the dumps are identical. craft-mime now reads the DOS pages by their IANA names (IBM437, cp850, ibm-852, 857...), which it read as UTF-8 before.

# craft-codepage
|
||||
|
||||
Legacy 8-bit code pages, one table each, for every reader of old text in the Craft libraries:
|
||||
|
||||
- the single-byte Windows code pages (874, 1250–1258) and Mac OS Roman (10000), byte by byte
|
||||
(`windows_byte`, `cp1252`);
|
||||
- the DOS (IBM PC, OEM) code pages 437, 720, 737, 775, 850, 852, 855, 857, 860, 861, 863, 864,
|
||||
865, 866 and 869 (`dos_upper`, the `dos` tables; `oem_byte` with the glyphs DOS shows for
|
||||
control codes);
|
||||
- document text in any of those (`code_page_byte`), Windows' symbol code page, the RTF/Word font
|
||||
charsets (`charset_code_page`), and the names of the East Asian multibyte code pages for
|
||||
`encoding_rs` (`multibyte_encoding_name`).
|
||||
|
||||
Everything is keyed by Windows code page number. Readers that name code pages another way map
|
||||
their names onto these: craft-dxf (`$DWGCODEPAGE` names such as `DOS850`), craft-mime (charset
|
||||
labels such as `IBM850`), craft-rtf (`\ansicpg`, `\fcharset`).
|
||||
|
||||
```rust
|
||||
use craft_codepage::{code_page_byte, dos_upper, windows_byte};
|
||||
|
||||
assert_eq!(windows_byte(1251, 0xC4), 'Д');
|
||||
assert_eq!(code_page_byte(850, 0x9B), 'ø');
|
||||
assert_eq!(dos_upper(437).map(|t| t[0x1B]), Some('¢'));
|
||||
```
|
||||
|
||||
The Windows and Mac tables match the WHATWG Encoding Standard's indexes, except that a byte a
|
||||
Windows code page other than 1252 leaves unassigned is U+FFFD here where the standard gives the
|
||||
C1 control of the same number. A test checks that against `encoding_rs`.

||||

||||
