[issue25200] bug on re.search using the char ,-:

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

This is how regular expressions work.

https://docs.python.org/3/library/re.html#regular-expression-syntax
Ranges of characters can be indicated by giving two characters and separating them by a '-', for example [a-z] will match any lowercase ASCII letter, [0-5][0-9] will match all the two-digits numbers from 00 to 59, and [0-9A-Fa-f] will match any hexadecimal digit. If - is escaped (e.g. [a\-z]) or if it’s placed as the first or last character (e.g. [a-]), it will match a literal '-'.
