If you translate into languages that use accentuated vowels like à, é, í, ó, ú and ã or õ and a set of punctuation that is not available in english, such as ¡ and ¿, you might see "weird" characters when opening the files with the translated texts.
The accentuated characters might show up like this: Ã© or â€©
Fixing this problem is really easy.
On the application you use to open the files (txt editor or word), go to preferences and set the encoding to UTF-8, like below.
