Werner Lemberg cba72a0b0f [pcf] Fix handling of the undefined glyph. 
This change makes the driver use the `defaultChar' property of PCF
files.

index zero and index `defaultChar' and adjust the encodings
accordingly.

PCF_Glyph_Load): Undo change from 2002-06-16 which always enforced
the first character in the font to be the default character.
