This script will get the codepoints (the numerical values that map to specifics characters) for any Unicode (or ASCII) text. Output is a space-separated list of the codepoints in hexadecimal notation.
Conversely, a list of codepoints (in hex) can be converted back to text. Values should be separated by a space character (or other whitespace — multiples ignored). Note that not all numerical values correspond to valid or displayable characters.
Uses: one obvious use is to obfuscate email addresses to block harvesting by spambots.
