Issue: "Unicode Highlight" feature suggests incorrect locale for ignoring common characters
Labels: feature-request,unicode-highlight

Type: <b>Bug</b>

1) Set Windows language to Ukrainian
2) Write a string constant `"росія - держава-терорист"` in an open code file
3) Hover over highlighted characters and click "Adjust settings"

In the popup it suggests to ignore characters common for "ru" locale, despite it not being used anywhere in the system. Moreover, manually specifying "uk" or "ua" locale in settings has no effect at all.
