The problem is actually worse than I first realized. Although an
isolated "h" can appear in the input without triggering the
exception, even strings like this one (note the embedded "ht")
trigger the problem:
a weightless experience
The generated lexer complains, "mismatched character 'l' expecting
set null".
There are no shortage of words in the English language containing
"ht" (try "grep ht /usr/share/dict/words | wc -l" or similar... I get
over 1600 on my system)... But I'm not so concerned about this
specific problem; I'm more worried about the general case because I
am certain this exact problem will crop up again in the future and
I'd like to know how to deal with it in a generalized way.
Cheers,
Wincent
