Work on named character functions for the Symbol Font.

I've finally found out why I can't print capital Upsilon - it is a special character so needs to be amp-hash-161-semi in SVG or forward-slash-Upsilon1 in PostScript. This is unfortunate as it contradicts how text encoding works in Wumpus-Core - currently an encoding (e.g. Latin1) is associated with a drawing, but it looks like it will have to be associated with a font / character set instead.
