Frequently Asked Questions
How does diacritic removal work?
The tool decomposes combined Unicode characters into base glyphs + accent marks via NFD normalization, then strips the diacritical mark ranges (U+0300 to U+036F).
Why is ASCII cleaning useful for legacy systems?
Many legacy databases, SMS gateways, and command-line utilities corrupt or drop multi-byte UTF-8 characters unless normalized to standard 7-bit ASCII.
