| The .psfu files have a built-in Unicode mapping, | |
| the .psf files don't. | |
| If you load a font (with setfont) without built-in | |
| mapping, then you'll have to provide one separately | |
| on the setfont command line. | |
| Eventually we expect that all fonts will have built-in Unicode mappings, | |
| and the .psfu files will be renamed .psf again. |
