Won't work.

But this is an FAQ:

http://www.tex.ac.uk/cgi-bin/texfaq2html?label=underscore

but I'm not finding those instructions helpful.

The solution should be something like:

- select a font which contains an underscore
- create a command which sets the character underscore as the glyph from the font
- (optional?) set a command which adds special information to the .pdf so that your screenreader says something which makes sense.
