Common Use Cases
Diagnosing encoding bugs
Compare the code-point sequences of two "identical" strings to find why they fail equality checks.
Building character tables
Generate code values for documentation, keyboard handling, or parser test cases.
Frequently Asked Questions
- How is this different from String to ASCII?
- Functionally they produce the same space-separated decimal codes for ASCII text; this tool emphasises the raw base-10 character code for any Unicode character, useful when debugging encoding issues.
- What can I do with decimal character codes?
- Diagnose invisible characters (a 8203 zero-width space breaking string comparison), build test fixtures for parsers, and cross-reference code points against Unicode tables when text behaves unexpectedly.
- Is my data private when I use this tool?
- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
