I am working on decoding text. I am trying to find the character code for the — character, not to be mistaken for -, in ASCII. I have tried unsucc
This character does not exist in ASCII, but only in Unicode, usually encoded by UTF-8.
In UTF-8, characters are encoded by 2- or 3-byte sequences (or occasionally longer), where none of the two or three bytes is a valid ASCII code, where all of them are outside the ASCII range of 0 through 127.
One suspects that the foregoing only partly answers your question, but if so then this is probably because your question is, inadvertently, only partly asked. For further details, you can extend your question with more specifics.
