I have a printed copy, so I can compare it with the output of

But don't expect too much.  Hyphenatation depends on fonts.  In my
thesis I used Knuth's (7 bit) fonts.  Because accented glyphs were
composed by the \accent primitive, I had to hyphenate many words

The reason is that \accent inserts a word boundary and \lefthyphenmin
and \righthypenmin are applied to each part of the word.  So it's very
unlikely that a word with accented characters is hyphenated

A few years later 8-bit fonts became available with "real" accented
glyphs.  No need to use \accent anymore.  This was a big step forward.
I must admit that I don't miss the good old days.

Please keep them.  ;)
