Hi Mason,

we are using ICU in quite a few installations and I am not aware of any
issues. Can you share what you tried exactly? Where did you search and
did to you get no results, the wrong results, too many?

Some things I am aware of:

- If your callnumbers contain spaces, you almost always want to do a
phrase search. Use IntranetNumbersPreferPhrase and
OPACNumbersPreferPhrase to make it the default in searches.

- If your callnumber contain some characters like ([]) etc. especially
if they are not a pair, try wrapping your searches in "".

- Turn on the UseICU option if it applies.

- Exact search with ,ext doesn't work with ICU to my knowledge. Might be
fixed in some Zebra versions, haven't investigated deeply.

Hope this helps,
