Description

'like' queries with escaped single quotes throw exceptions

Seems to be due to geotools CQL round-trip. The following snippet fails:
ECQL.toFilter(ECQL.toCQL(ECQL.toFilter("name like 'name''1'")))

Research direction

Start by reproducing the failure with the provided ECQL.toFilter and ECQL.toCQL round-trip snippet. Trace the GeoTools CQL parsing and serialization path involved in escaped single quotes, then add or update a regression test for the expression. Done means the round trip completes without throwing an exception.
