But by design. IIUC the search engine for the Find toolbar uses the ICU lib
transformation to make search insensitive to diacritic markings (e.g. tilde,
acute, caron, etc.) meaning the Find toolbar search will return both 'ene' and
'eñe' of Spanish scripts as they are treated as the same base for Unicode
This was a design decision to keep the <Ctrl>+F find bar lightweight, and
applies equally to all scripts and locales.
The more robust 'Find & Replace' dialog provides the 'Diacritic-sensitive'
checkbox. It is enabled by default for all locales, and the search with ICU
libs does not combine the codepoints. Search for specific glyphs (U+00D1 LATIN
CAPITAL LETTER N WITH TILDE), or (U+00F1 LATIN SMALL LETTER N WITH TILDE)
