Multilingual UI Length Checker — illustrative example

INPUT
Button limit is 10 Unicode code points. English Save has 4; French Enregistrer has 11.

RESULT
Save passes the supplied character limit. Enregistrer exceeds it by 1.
Review the translated button in the actual font and layout before shortening it or changing its meaning.

REVIEW
UI text length checks need an explicit counting rule and real layout testing. Character count is a screening signal; glyph width, font, wrapping and placeholders determine whether text fits.

This is a teaching example, not a live execution record.
