Thanks all for your answers.
I am using Vim with terminals Mrxvt in Linux and iTerm2 in the Mac.
I have the same problem in Gvim as well.

Mostly. Over here, with:

VIM - Vi IMproved 7.3 (2010 Aug 15, compiled Apr 18 2012 19:32:03)
Included patches: 1-496

these Alt mappings work for me in more cases than not:

" Putting åæø and «» on Alt, is handier than digraphs:
inoremap <expr> <A-a> "\uE5"
inoremap <expr> <A-e> "\uE6"
inoremap <expr> <A-o> "\uF8"
inoremap <expr> <A-<> "\uAB"
inoremap <expr> <A->> "\uBB"

They work fine in insert mode, and for single character replacement,
using "cl", but fail when using "r". e.g.

Applying "cl<A-a>" to "x" gives å, which is correct.
Applying "r<A-a>" to "x" gives á, which is wrong.

As you can see in my first post I a mtryin to map <M-t> to <C-W>v,
So Alt+t will make a vertical split.
But looking at your mapping examples seems I am doing the map wrong.
Probably is because Vim sends the unicode keymao rather than the keymap I expect.
What would be way to, let's say make my Alt-t keymap:
nmap <M-t> <C-W>v
But using unicode?
Thanks

Maybe that has been fixed since patch 496. I've just learnt to use "cl"
instead of "r" - it's more flexible, anyway.
