What is ASCII to Unicode?
Every character has a Unicode code point. This converter shows the U+XXXX format for each character, plus decimal and hex equivalents for ASCII and extended ranges.
How it works
We iterate through each character, call charCodeAt for the BMP and handle surrogate pairs for characters above U+FFFF.
