codepage 1252 missplaces question mark on conversion

[arludwig]

When I converted a set of characters (0x20 to 0xFF) from CP1252 to source code, the question mark inside the filled diamond also got assiged the number 0x3f (regular question mark), where it should have gotten number 0x81. (My font was Arial size 9.)

When I exported with character sorting, the regular question mark got replaced with the diamond one. When I exported without sorting, Arial09_0x3f and image_data_Arial09_0x3 got created twice, once for each variant of the question mark.

#if (0x0 == 0x0)
  // character: '?'
  {0x3f, &Arial09_0x3f},
#else
  // character: '?' == ''
  {0x3f, &Arial09_0x},
#endif

#if (0x0 == 0x0)
  // character: '�'
  {0x3f, &Arial09_0x3f},
#else
  // character: '�' == ''
  {0x3f, &Arial09_0x},
#endif

EDIT: added revision info to header extract

[riuson]

Character 0x81 is missing in encoding CP1252.

In revision e5ae407, a partial workaround for this problem is added, as well as an optional skip of such characters when converting to a font file.
