dotnet build produce invalid path when Cyrillic characters

I have with Cyrillic names. dotnet build when report errors produce intelligible paths
```
ГенераторЗадачок.Ядро net10.0 a échoué avec 3 erreur(s) (9,7s)
D:\d\github\????????????????\????????????????.????\Library.fs(92,15): error FS0025: Incomplete pattern matches on this expression. For example, the value '?????????????? (_, _)' may indicate a case not covered by the pattern(s).
D:\d\github\????????????????\????????????????.????\Library.fs(342,19): error FS0025: Incomplete pattern matches on this expression. For example, the value '?????????????? (_, _)' may indicate a case not covered by the pattern(s).
D:\d\github\????????????????\????????????????.????\Library.fs(419,19): error FS0025: Incomplete pattern matches on this expression. For example, the value '?????????????? (_, _)' may indicate a case not covered by the pattern(s).
```

Start by reproducing the reported dotnet build failure with Cyrillic characters in the project and path names. Inspect how the errors referencing Library.fs are rendered, and consider the issue complete when those paths and related names remain readable instead of becoming question marks.
