    x11font: fix handling of high-bit-set SBCS characters.
    
    I had mistakenly pulled a 'char' value out of a string and passed it
    to x11_font_has_glyph and x11_char_struct, each of which takes its two
    index bytes as int-typed parameters. But if chars are signed, that
    turns high-bit-set characters into out-of-range array indices. Oops.
    
    The range checks in x11_char_struct prevented that from causing any
    problem worse than refusal to display any affected glyph. Even so,
    that's not particularly helpful. Fixed by changing the index byte
    parameters to unsigned char type.
