Part 1 of a two-part revolution in Linux console graphics. Map all the line-drawing Unicode characters to similar glyphs. This means all our nice corners freely translate into rigid corners etc in the console, rather than hateful default characters (usually black diamonds). The demo and all widgets now look correct when drawing lines and boxes. Next, we'll add the actual glyphs for the block-drawing characters, and we'll have the finest graphics ever seen on a text-mode Linux console. #201
Certain unit tests required UTF8 encoding on the output
terminal to work (#428). This includes anything which does
any kind of fill. Add enforce_utf8() checks to all such
tests that were missing them. Unit tests once again pass in
a pure ASCII environment.
