Comment 11 for bug 937605

After reading multiple bug reports about the 'UnicodeDecodeError' and taking another look Serge's bug report, I have to slightly change my description about my issue a bit. I get the UnicodeDecodeError not at startup but more specifically after activating any snippet. Errors weren't shown at starting Vim whatsoever.

I also narrowed the problem down to this bit in mswin.vim:
------------------
if has("gui")
  noremap <M-Space> :simalt ~<CR>
  inoremap <M-Space> <C-O>:simalt ~<CR>
  cnoremap <M-Space> <C-C>:simalt ~<CR>
endif
------------------

After commenting this out I am no longer receiving the UnicodeDecodeError as mentioned above. Now this may be a specific to my issue/configuration, but maybe it affects others as well.
