I normally use the Kanji draw [1] application which is also surprisingly good at
recognizing what I'm trying to input. Not nearly as forgiving as Google's
solution [2], which I sometimes have to fallback to, but usually it works if I
can at least roughly guess what the official way of drawing a character is and
check for inexact matches. Plus it's FOSS.

to draw kanji. If you just draw something any old way that looks like it, it
certainly won't be recognised."
