CharRest is a graphical tool, written in Python, that can be
used to restore text accidentally saved in a wrong charset.

For example, it can convert the following corrupted text:
ÂÜëå öùôéÜ óå üôé óå êáßåé óå üôé óïõ ôñþåé ôç øõ÷Þ
back to it's original form:
Βάλε φωτιά σε ότι σε καίει σε ότι σου τρώει τη ψυχή

CharRest requires pyGtk 2 (installed by default on linux) and  iconv.
