Charcode decode
Charcode decode. Runs on your device, nothing is uploaded.
Charcode decode takes decimal numbers separated by spaces or commas and converts each into the Unicode character at that code point. A non-decimal group gets the run refused, with that group and its position named. A number past the valid Unicode range is refused the same way, and empty input with no groups is refused too.
Questions
What number format does it expect?
Decimal Unicode code points, separated by spaces or commas.
What happens with a value above the valid Unicode range?
The tool refuses, naming the group that exceeded a valid code point.
What if a group is not a plain number?
The tool refuses, naming the invalid group and its position.
What if there are no groups at all?
The tool refuses with "no charcode groups found in input".
Can I use this from the command line?
Yes, the same code runs on the page, the CLI and MCP.
