Hi!
While rebuilding the python related packages against the Python 3.15rc1
version we found that wtforms fails to build from source [1].
The build fails with errors like this one:
AssertionError: Expected value 1’23’456.789 to parse as a decimal,
instead got ['Keine gültige Dezimalzahl']
This is due to changes in Babel 2.18 (CLDR 47), which changed
babel.numbers.get_group_symbol("de_CH") from \` to \'
I've added a patch to support this. The patch should be forwarded
upstream
I applied the fix in the sandbox [2] to be able to build the packages
that depend on wtforms, please consider applying the patch to support
the upcoming 3.15 version.
Happy hacking,

Subject: tests: Use Babel group symbol for de_CH
In Babel 2.18 (with CLDR 47), the thousands grouping separator for de_CH
changed from '’' to '\''. Use babel.numbers.get_group_symbol to retrieve it
dynamically.
