Micromamba fails to bootstrap with non-65001 codepages

[wfjsw]

Troubleshooting docs

• [X] My problem is not solved in the Troubleshooting docs

Anaconda default channels

• [X] I do NOT use the Anaconda default channels (pkgs/* etc.)

How did you install Mamba?

Micromamba

Search tried in issue tracker

65001, Utf-8

Latest version of Mamba

• [X] My problem is not solved with the latest version

Tried in Conda?

I didn't try

Describe your issue

Micromamba is having this kind of issue when:

• The code page is not 65001 (aka. the Unicode checkbox is not checked)
• There is Chinese character within the CONDA_DEFAULT_PREFIX environment variable

AFAIK adding /utf-8 argument to MSVC could force 65001 and have this issue fixed but I cannot spin up GitHub Actions for 1.5.6 to produce a binary.
