Why not just have support for aspell (
http://aspell.net/) which has support for many languages and can be installed only if the users want it?
As a paid user I fully support this. There is no reason why the author should be overly concerned about supporting different languages when that's the job of the spellcheck library, use aspel or hunspell as notepad++, LibreOffice, OpenOffice, Firefox & Thunderbird and Google Chrome either are doing, or have used in the past, and let the users download the languages they want seperately themselves.
