Request

Please confirm whether this is a known issue with Unicode paths in the
Windows installer.

Provide an official fix/patch or documented installer parameters to force an
ASCII-only temp/output path for locales.txt without changing the Windows
account.

If an updated build is available, we’d be happy to test it.

Best regads,
Nick
