Grapheme is:

graph.eme /'gra-"fEm/, noun [1935]

   1) the set of units of a writing system (as letters and letter
      combinations) that represent a phoneme

   2) a unit (as a letter) of a writing system

The difference between grapheme and glyph is that a glyph is a single
visual unit of a script, whereas a grapheme is a single logical unit; for
example, until recently, "ch" and "ll" were graphemes in Spanish even
though both were composed of two glyphs.  (Or at least that's my
understanding of it.)
