"←  " message in log when mapping Sanger reads

Scenario:

1. Set log level to "DETAILS".
2. Open "Tools > Sanger data analysis > Map reads to reference".
3. Input an appropriate reference and reads, click "Map".
   Current result: In the log there is a message "Reads accepted by the mapper". After that there are messages for the mapped reads that contain strange text with 2190 code and nbsp.

Source code
The problem is in the method QVariantMap AlignToReferenceBlastWorker::getResult(Task *task, U2OpStatus &os) const in AlignToReferenceBlastWorker.cpp:

foreach(pair, acceptedReads) {
        algoLog.details((pair.second.second ? "←  " : "→  ") + pair.first);
    }

Replace a string with 2190 with "[REVERSE] ", a string with 2192 with "[FORWARD] ".
