Locale file highlighter for Vim

Glibc uses locale (or fdcc) files to define cultural conventions. The files are usualy named
xx_ZZ where xx is the ISO language code and ZZ is the ISO country code.
Main features:
- highlights only valid keys with various LC_ sections
- Shows bad < UNNNN > unicode as an error
Installation
- Copy the file to your .vim/syntax directory in a locale file type: set syntax=fdcc
Filetype detection
Slightly harder as locale files do not have any specific suffix - but heres what to do
Insert this after the Diff section in your scripts.vim file. It does initial patern matching and then looks within the file to determine if it is a locale file.
The double quotes below are escaped on this site so remove those escapes. In fact it will probably mess up all back slashes aswell.

while getline(lnum) =~ "^? " && lnum < line("$")
