Cannot search for strings containing double quotes

[badaz]

When using contains(), it is not possible to have search terms containing double quotes. The error is "Invalid predicate". I had to stop using the lib to have my query work.

Not working with realm-query:

items = RealmQuery
        .where(realmStorageManager.getRealm().objects('Ticket'))
        .beginGroup()
          .contains('fullnameCanonical', filterCanonical, true)
          .or()
          .contains('fullnameCanonicalReverse', filterCanonical, true)
        .endGroup()
        .findAll()
      ;

I also tried to escape the double quotes the JSON way with backslashes, it does not crash anymore but does not find the matching items which do contain double quotes

Working without realm-query:

items = realmStorageManager.getRealm().objects('Ticket')
        .filtered('fullnameCanonical CONTAINS[c] $0 \
          OR fullnameCanonicalReverse CONTAINS[c] $0', filterCanonical)
      ;

I googled my problem and found someone saying we should always use the $N to pass strings, maybe this is the problem with this lib.
