There are many programs in SliTaz can work only with UTF-8, but they designed to work with many encodings. There are LeafPad, Beaver, Midori, Poedit and Claws Mail. I received some emails in other than UTF-8 encodings, there is Cyrillic windows-1251 and KOI-8R. I get only underscores (_) instead of cyrillic symbols in Claws Mail. Function in menu View - Encoding don't work. I want to open this email's file in Firefox, set correct encoding and read text. But, Firefox is thing-in-itself.

Maybe the problem with encoding in all SliTaz programs have common roots? Maybe it lacks a global library for conversion?
