Strip accents from names for ASCII-only systems

José → Jose, Zoë → Zoe, Łukasz → Lukasz — when the form, airline or database only accepts A–Z.

The job

Booking systems, legacy databases and slug fields often reject anything outside A–Z. Removing accents is lossy — but when the field demands it, doing it predictably beats guessing.

Decompose, then map the specials

Paste the text and run. Combining marks (´ ¨ ˜ …) are stripped via Unicode decomposition; letters that aren't decomposable (ß, ø, ł, æ, đ…) are mapped per the option you pick — expand (ß→ss) or drop-to-nearest (ø→o).

café → cafe, naïve → naive, Łódź → Lodz.
CJK, kana, Cyrillic and other non-Latin scripts pass through untouched — this is not a transliterator.

Check names against documents

Passports and tickets care about exact letters: ICAO rules transliterate ß→ss but the booking field may expect the bare letter. Compare the output with the travel document before pasting it into a ticket form.
