qt5base-lts/tests/auto/wasm/tst_qwasmkeytranslator.cpp
Mikolaj Boc 3dc6fdc6d8 Fix the handling of dead keys and test the mechanism 
An effort has been made to support more keyboard layouts that provide
dead keys (US international, Mac-specific dead keys).

The dead key is translated now at the event conversion phase, not
when it is actually used for modifying keys, which simplifies the logic.

Unittests have been created to check the translation mechanism.

Fixes: QTBUG-86272
