[edit]Lower half of Dos Code pages
[edit]Code page 850 cites both IBM[1][2] and the International Components for Unicode[3] in the header of the table describing the layout of the code page. IBM[1] and the article provide a table where the characters at positions 0x00–0x7F match Code page 437, but International Components for Unicode provides a mapping[3] that instead agrees with ASCII including ASCII control codes. The IBM mapping[2] agrees with the IBM table not the Unicode mapping. Is the situation here something like the whole ISO 8859-1 vs Windows-1252 thing, or is one of the sources just wrong?
Other Wikipedia articles on Dos codepages have similar issues, but some only provide a table for the upper half and state that the lower half is the same as Code page 437. What should the articles say? McYeee (talk) 20:08, 23 August 2024 (UTC)
