No.  The problem is that there is no one-to-one mapping.  For example,
many fonts use a single glyph for all character codes which are
unknown.  Additionally, at least for TrueType and OpenType fonts, it
is basically impossible to get this information if glyph substitution
within glyph contexts is active, as necessary for e.g. Arabic or Indic
scripts.  An extreme example might be that the character `A' maps to
seven glyphs which appear as the string `America'.
