Can I change the word breakers of specific language in full text search engine?

Hi every one I wanna use full text search for Persian Language as I know that this engine does not support Persian language people were suggested me to Use 'Arabic' or 'Neutral' for full text search engine The problem which I encounter is I have to omit some word breakers of these language .In Persian we use 'Half Distance' word breaker as a character in single word but both 'Arabic ' nor "Neutral' language knows this character as a word splitter and the result of search contain some part of single word not the whole word for example : if someone search for the word 'ایرانی‏ ها' which between 'ایرانی' and 'ها' is not complete space it is half space the result of search look for '' and '' as separate words while 'ایرانی ها' is a single word. I really appreciate anyone who would help me in this problem. Thank you all
