Well, the point here is that it just performs some really hackish
translation to CP437, not CP850, on the output path. It is really not
robust. Copy-pasting is also broken because of it, because it pastes
CP437 characters.

This is a known issue, since there is no translation from Unicode code
points to UTF-8 sequences. In other words, if you press ë, the keyboard
layer will properly send a 235 to Syscons, but instead of encoding it as
0xC3 0xA9, will just emit a single byte, having value 0xE9.

Maybe a patch like this could already get that working, but it's just a
quick hack.
