I use very often UTF-8 files for my Extension Firefox translation in French.
It uses UTF-8 files without signature (BOM Byte Order Mark).
To see the news of the extension, I use the Compare By Content... function that works right. The UTF-8 file are bad shown but it is made in the same way in the 2 compared files.
But if I use the Edit mode function and save the changes made, all the special characters (already in the file) are updated to something bad


Best regards
