What encoding do you have set in preferences?
Encoding: Character set to be used for encoding. All new files will be created with the new encoding, and the new encoding will be used to open and save files that do not have encoding tags.
It was cp1252, Now i found the place where to change encoding. I changed to UTF-8 and it's working now. Would you recommend UTF-8 in a windows environment or would you choose another encoding?
