trial and error

the tool you want is iconv: put you text into a file and convert it usind iconv (I don't know if there is a GUI tool). or if you only want to convert filenames (rename them) you should check convmv.

concerning detection of the source charset I don't know of any tool for the job. as far as I know you only choice is trial and error, meaning that you guess the source encoding and check whether the output is as you want it.

Hello.

Try `konwert':
Code:
cat file | konwert any/ru-koi8r | less
This is for Russian language and koi8-r codepage. You can detect the codepage of your text by using smth like this:
Code:
cat file | konwert any/ru-test
`any' means any codepage, `ru' means Russian.
From manpage:
Code:
Currently supported languages are  cs (Czech), de (German), 
el (Greek),  eo (Esperanto),  es  (Spanish), fr (French), 
he (Hebrew), it(Italian), pl (Polish), pt (Portuguese),  
ru (Russian),and sv (Swedish).
Konwert uses statistical analysis for codepage detection.

Hope this is useful. Bye.

P.S.: I don't know is there a C language API to konwert's functionality (iconv have such API). I think, no.

as far as i know, there is no way to know the typeset of a string... and it is the same for a raw text file, the only thing you could try is to guess the typeset from what is in it, but not much more...

Arrow

To detect source charset I use package enca. Homepage: trific.ath.cx/software/enca/ (to workaround url pub limit).
