Remove Non-ASCII Characters
Keep basic ASCII text and remove emoji, accents, and other Unicode characters.
How Remove Non-ASCII Characters works
Remove Non-ASCII Characters handles characters outside the original 128-code-point ASCII range while preserving English letters, digits, basic punctuation, spaces, tabs, and line breaks. The filter walks Unicode code points and retains only values from zero through 127, so accented letters and emoji are removed rather than approximated or transliterated. The Remove Non-ASCII Characters exposes its text controls so this particular convention stays inspectable instead of hiding behind an unexplained preset.
The default café plus emoji sample becomes caf followed by its original space; the accented e and the emoji are both outside ASCII and therefore disappear. Developers can prepare strict legacy-system input or diagnose which visible content depends on Unicode rather than silently converting it to look-alike characters. The Remove Non-ASCII Characters presents a deterministic plain-text result that can be copied and compared with the worked value before it enters another workflow.
Limits and private processing
Removal can lose meaning and names. If you need café to become cafe, use a diacritic transliterator instead of this strict ASCII filter. The Remove Non-ASCII Characters performs its complete operation locally in your browser; neither the source text nor its settings are uploaded, stored remotely, or sent through an external request.
