Box drawing characters #9

Open martinthomson opened 2 years ago

martinthomson commented 2 years ago

There is some limited support for these in the tool, but that support needs a fair bit of work. Do that work.

Just out of curiosity, is this issue about supporting box drawing characters as input or as some sort of rendered output?

I would personally be happy if we could use them as input, as an alternative to the current 7-bit clean |, -.

Yeah, the goal is to properly recognise all the various box drawing characters as input. Some are already recognised, but nothing comprehensive.

Here is a test vector, that would be useful if it could be transformed safely by aasvg:
