[BUG] The search for Cyrillic words does not work

[VladWinner]

Describe the bug
The search for Cyrillic words does not work: "Search returned 0 results."

To Reproduce
Use deep search in localizations for "Трилинейная" or any other Cyrillic/Russian word.

Expected behavior
This should display the results that exist and usually are visible if I do a search using the keys ("EUI_TEXT_OPTIONS_GRAPHICS_TRILINEAR") or the English value ("Trilinear").

Workaround for regular modders: use any UTF-8 to Windows-1251 converter to make the search work
(e.g.: https://involta.ru/tools/decoder/)

Трилинейная → Трилинейная
