the reason is that i dont want to get ppl confused.
we have english books and hebrew books. but every book (english or hebrew) has two titles. one in hebrew and one in english. (why? never mind

)
search text: any text
book language: the books language
language search:
search the title in hebrew or english
u can see it might be confusing.
so my questions would be:
1. how can i change a letter in the variable LETTER into a hex number?
2. how can i change an encryption of a single letter (only to this single letter). in case the user isnt typing unicode, i will have to change it to unicode.
