It would be interesting to know if it's CHR or ICU indexing for Zebra.

These symbols get stripped out in the normalization process. With phrases in
ICU, I see we're arbitrarily removing all punctuation. With words in ICU, it
looks like we might only be removing punctuation that is preceded by whitespace
(which seems to imitate the example chain.xml from
https://software.indexdata.com/yaz/doc/yaz.pdf). So that might be OK. In fact I
should be able to test that...

With CHR indexing, symbols get converted into spaces, so it won't work.
