Let's take 文 kanji for example:
I can find words for its most popular readings - もん、ぶん、ふみ：
But here it says there are two other readings - あや and かざる - but i can't find words for them!! (google, wiktionary, jisho.org do not help!)
Or kanji 局 - wiktionary mentions this reading しきる
But where is it used that way??
The question is How can i find words for these less popular readings?
