What is ASCII Codes Converter?
This converter walks through your input character by character and emits the Unicode code point of each one, formatted either as a decimal number or as hexadecimal. The decode side accepts a list of code points separated by spaces, commas, or newlines and reassembles the original text. Hex tokens may optionally be prefixed with 0x or #. The tool handles characters outside the basic ASCII range, including emoji and supplementary plane code points.

FAQ
- Does it support Unicode beyond ASCII?
- Yes. Code points up to U+10FFFF are emitted and accepted, so accented letters, CJK, and emoji round-trip correctly.
- What separators work for decoding?
- Spaces, commas, semicolons, and newlines are all accepted between numbers — mix them freely.
