Output wrongly includes control characters `````[1;34m`

[paternal]

Since Python3.14, argparse --help output is colored, which is rendered by sphinx-argparse as �[1;34musage: �[0m�[1;35mfancytool�[0m [�[32m-h�[0m] (instead of usage: fancytool -h).

This can be controlled by environment variables.

Minimum working example: Just run any of your usual example with python3.14.

Can confirm. I see the odd colour control characters when building documentation with .\make.bat html and with python -m sphinx -b html. But not when running through PyCharm, probably because it disables colour coding.

I guess we could either filter all color characters from the argparse result, or try to disable colour features when running argparse. I'll have a look and see what's possible.

EDIT: In an IDE the issue can be made to appear while debugging by passing FORCE_COLOR=1 as an environment variable (see https://docs.python.org/3/using/cmdline.html#controlling-color).
