Based on other discussions on this site and elsewhere, using flags to identify languages is the path to madness.
Nevertheless, I need an easy way to identify the language of individual content items on my site. I was thinking a bracketed 3 letter prefix might do the trick:
[ENG] - English
[FRE] - French
[FRA] - French (better?)
[ITA] - Italian
[SPA] - Spanish
[ESP] - Spanish (better?)
[GER] - German
[JPN] - Japanese
[CHN-S] - Chinese Simplified
[CHN-T] - Chinese Traditional
etc...
Apart from the special case for Chinese's two distinct systems, would I run into any problems sticking to a 3 character prefix system?
