I think we want to backport this to 7.x

[thaystg]

/backport to release/7.0

Started backporting to release/7.0: https://github.com/dotnet/runtime/actions/runs/3444998494

[github-actions]

@thaystg backporting to release/7.0 failed, the patch most likely resulted in conflicts:

Please backport manually!

@thaystg an error occurred while backporting to release/7.0, please check the run log for details!

Error: git am failed, most likely due to a merge conflict.

@thaystg @ilonatommy Was this reproducible only with Blazor? Was this reproducible without VS?

State before the fix.
Special signs in path (#):

• wasmbrowser on Browser: OK
• wasmbrowser on VS: OK
• blazorwasm on Browser: OK
• blazorwasm on VS: OK

Diacritic signs in path (żółw):

• wasmbrowser on Browser: NOT OK (a mess in finding files)
• wasmbrowser on VS: OK
• blazorwasm on Browser: NOT OK (files names are found but loaded without content and under a wrong tree)
• blazorwasm on VS: NOT OK

EDIT:
my bad, now when I checked more systematically, it turns out that this introduces a regression.

After fix:
