The file /usr/share/vim/vimfiles/after/syntax/lisp.vim contains the line set enc=utf-8 which changes the internal encoding of Vim. This gives problems on system that does not use utf-8 as the system encoding. The solution is probably to use 'fenc' instead of 'enc', which sets the encoding of the file. Reproducible: Always Steps to Reproduce: 1. Change system encoding to Latin-1 2. Open a Lisp-file in Vim Actual Results: Non-ascii characters are not recognized correctly, nor are meta-bindings if your meta key sets the 8th bit in your terminal.
Created attachment 213416 [details, diff] Patch to apply to source to get requested behaviour.
Created attachment 213418 [details] Updated ebuild to apply the vim-syntax patch. Applies the vim-syntax patch to source before building.
Looks like this ebuild has been superseded by newer versions. If this is still an issue, let us know and we'll get this change submitted to the ebuild; otherwise, I'd like to close this issue within a week or two. If I don't hear anything by September 13, I'll assume that it's no longer an issue and close this bug as invalid.
