Pseudoloc
Which strings on this page were never sent for translation?
Pseudo-localisation answers two questions at once and neither has any other cheap answer. A string that comes back unaccented was never routed through the translation layer; a button that breaks its container at forty per cent expansion will break it in German, Finnish or Russian. Both are visible in a single glance at the page.

What this actually is
swap copy for pseudo-locale to find hard-coded stringsBefore a site is localised, and before every release after that - a hard-coded string is the sort of regression that ships in a hurry and is found by a customer.
Asked about this tool
4 of themWhy is the text longer as well as accented?
Because the two failures are different. Accents find strings that skipped the translation layer; the extra length finds containers sized to English. A pseudo-locale that only accented would miss every truncation bug.
Does this change anything permanently?
No. It is a live edit like every other one here - Clear LoupeKit changes puts the copy back and a reload was always going to.
Why does the panel’s preview match the page exactly?
Because it calls the page’s own transform rather than reproducing it. Two implementations of a pseudo-locale is two answers to the same question.
Can I change the character set?
Yes, and the setting is one record read by the tool, the page bar’s card and the page itself - so all three always agree about which locale is running.
