The bug bit me some time ago (not in context context, but with pdftex)
when the glyph-to-unicode map embedded into PDF document was flawed in 
this way and thus export to plain UTF text and searching were broken.

When AGL is used to map from adobe glyph names to Unicode I do not see
  how things can potentially be broken by the proposed fix,
  but if the Type1 fonts support is considered frosen,
  then there is a point in not touching it unless it is
  something really severe, what my issue definetely is not.

  Sincerely, Michail
