This is not a good idea. Lots of string functions truncate data when finding a end of string character (null character).all integers from 0 to 255 have a null character in the first eight bits, so it's a little dangerous to use byte data inside strings. I recomand you to use banks (much better).
Anyway, you can always put the INT into a Bank, and read the bank into a string.
