[New-bugs-announce] [issue42676] zoneinfo uses locale depending functions for parsing

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

zoneinfo uses locale depending functions isalpha(), isdigit(), isalnum() to parse data. It may be correct when parse the TZ environment variable (although they do not work with multibytes locale encodings like UTF-8), I think that parsing the content of data files should not rely on current locale. Later the parsed data is decoded implying UTF-8 (for abbr) or ASCII (for numbers).
