Logging a unicode character to a file fails on Windows

[lyovushka]

Have you checked closed issues? (https://github.com/Textualize/textual/issues?q=is%3Aissue+is%3Aclosed) Yes

Have you checked against the most recent version of Textual? (https://pypi.org/search/?q=textual) Yes

Here is an example to reproduce the issue:

import os
os.environ["TEXTUAL_LOG"] = "log"

import textual

textual.log("：")

On Windows this crashes with:
UnicodeEncodeError: 'charmap' codec can't encode character '\uff1a' in position 0: character maps to <undefined>

It would be relatively easily fixed by specifing encoding="utf-8" when opening the log file in src/textual/__init__.py. But to be honest I am not completely sure what is the recommended way of dealing with encoding issues in python. Maybe it is up to the user to make sure the encodings match.

The log file should be opened in utf-8. Feel free to open a PR.
