What is the counter word for kanji?

I was wondering what is the counter word for kanji and I couldn't find a realiable answer online, so I asked my Japanese teacher, 絵理子先生. The answer is surprisingly simple. One of those that when one sees them, one things to oneself, duh! Without further ado, for counting kanji in Japanese you can use 一ひと文も字じ、二ふた文も字じ or 一いち字じ、 二に字じ. Now, trick question. How do you count 感かんじ?
