Aah, I forgot that.  Then you don't need an optional argument to
\etxtoenc, of course.

Hmm.  Assume that glyph `foo' has index 1 in the AFM file and `bar'
index -1.  Without the above \let, the names within fontinst for those
two glyphs are `foo' and `bar-not'.  If I have e.g.

  \Ligature{LIG}{foo}{bar}{foobar}     ,

fontinst emits a warning that glyph `bar' isn't available, and I had
to write


to overcome this.

Am I missing something?  Actually, I can't see any reason to ever use
\setnotglyph in case an ETX file is used.  Can you give an example for
a useful \setnotglyph?
