Here is an updated version that uses +/- buttons.

The categories Cn, Cs, and Co are now hidden by default.

For some reason, raw bytes also belong to the Cn category so are not
shown by default.

I discovered that Emacs displays 8-bit control codes the same as raw
bytes, e.g. the char-codes #x82 and #x3FFF82 are both displayed as \202.
I think this is confusing.

I added that, too.
