Revise the fix for #hasGlyphForCode: from Graphics-mt.468 ... of course ... we must check +1 and +2. I even said so in the commentary. Sorry for the noise.

=============== Diff against Graphics-mt.468 ===============

Item was changed:
  ----- Method: StrikeFont>>hasGlyphForCode: (in category 'multibyte character methods') -----
  hasGlyphForCode: aCharacterCode
  	"Note that missing glyphs are encoded as -1 in the xTable but to speed up the #widthOf: check, the next offset must be adjacent and thus be duplicated. For example: #(-1 -1 0 24 -1 -1 -1 24 48 -1 ...). Since aCharacterCode is 0-based, that codes offset is at +1 while its width needs to consult +2, too. See #widthOf:." 
  
  	(aCharacterCode between: self minAscii and: self maxAscii)
  		ifFalse: [^ false].
+ 	(xTable at: aCharacterCode + 1) >= 0
+ 		ifFalse: [^ false].
  	(xTable at: aCharacterCode + 2) >= 0
  		ifFalse: [^ false].
  	^ true!
