[New-bugs-announce] [issue31672] string.Template should use re.ASCII flag

[INADA Naoki]

New submission from INADA Naoki <songofacandy at gmail.com>:

Currently, strings.Template uses re.IGNORECASE without re.ASCII:

    idpattern = r'[_a-z][_a-z0-9]*'
    flags = _re.IGNORECASE

[a-z] matches against 'ı' (0x131, DOTLESS I) and 'ſ' (0x17f, LONG S).
It is not intentional, and it makes re.compile slower.
