I'm using the EurKEY keymap on my US keyboard:

Does that show up as non-gibberish for you? E.g., aside from the
n-with-tilde, and e-with-accent, it's just lines that I associate with ANSI drawing and math symbols.
Anyway, I have a Spanish keyboard (as in, from Spain), and have AutoHotKey
set up so that I can type an esset (looks like a fancy B). So, outside of BBS land, I have no problems typing Spanish characters, or things with umlauts, etc.
But my Alt-Group keys don't work through SyncTerm or MagiTerm, and I assume there'll still be issues with the character set, since it predates things
like the Euro character.
