| UPDATES %%%%%%%% found that suppose you have unicode rendered within javascript, it can very much be used as a literal, and will infact match identically to the same unicode word found elsewhere within the HTML DOM. also, even though the to_XXXX did no throw any errors, it wasnt showing the correct possible because N number of binaries/list does not necessarily mean N symbols (a symbol can be formed by more than a series of binary elements) an excellent utility that helped me easily evalute the decimal/binary/hexa values of unicode symbols (just paste them into a text area to see results) was located at http://software.ellerton.net/txt2bin/ ~b101 |
