It's only in a specific KRunner plugin, so it won't work in any other thing finding apps by name using lower-level APIs. And it only works for Chinese. Littering high-level frontend code with language-specific stuff seems wrong. Is there a more central place we could put this, and maybe a more extensible way to do it? Like, a framework like Ki18n could have a matchInput(haystack, needle) that can do this sort of language-specific expansion/transform for haystack to match needle.

A framework API used transparently in places where it makes sense, and extensible to other languages: Maybe. But really the general place where pinyin to Chinese conversion happens is IME. If you want an automagic IME, that should maybe implemented at the Qt input handling level somehow.

Sure pinyin needs an IME :P

FWIW: I live in Seoul.
