Sublime Text 2 allows the user to add a new spelling dictionary. For example: to install a Polish dictionary on a Mac, you can download a MySpell dictionary and unzip the files (pl_PL.aff and pl_PL.dic) it into the following path:
~/Library/Application Support/Sublime Text 2/Packages/Language - Polish
The spell checker can then be activated by selecting from the View > Dictionary menu.
Unfortunately the spell checker can only handle words without any accented (extended Latin) characters.
Any word with such a character is considered to be misspelled and is underlined.
In order for the spell checker functionality to make sense, this bug must be fixed.
