Expected behavior

Copying non-ASCII characters between Windows and WSLg should work

Actual behavior

In this example I am copying a string "ááá" from notepad.exe to gedit and gvim. In both cases gedit and gvim seem to expect UTF-8 encoded data but it looks like they receive ISO-8859-1 (latin1) where "á" is encoded as 0xE1.

Yes, we are aware of this, the possible solution is to support conversion between CF_UNICODETEXT (at Windows) and utf-8 (and optionally utf-16) in WSLg side.

Fixed in 1.0.23.
