Hmm, this is interesting. Kanji 戋 0x620b is not present in the Kanjidic, neither is マ (it is katakana letter MA). Therefore, I cannot obtain proper entries for those two characters and therefore they cannot be further worked with, unfortunately.
There is however something you can do: can you please ask Jim Breen to add this specific kanji 戋 0x620b to the kanjidic?
I'm not sure if I understand correctly. AFAIK there is exactly one free Kanji database, the Jim Breen's Kanjidic2: http://www.edrdg.org/kanjidic/kanjd2index.html
Jim have put a lot of effort and energy into creating that database, I believe he deserves to be contacted in person. I have dropped Jim a mail, I hope he will find some time to discuss this issue.
Kanji 戋 0x620b is not in the Kanjidic2 database because it's not in any of the 3 JIS standards that identify the kanji used in Japan (JIS X 0208/0212/0213). See: http://www.unicode.org/cgi-bin/GetUnihanData.pl?codepoint=%E6%88%8B
It may seem an arbitrary limit to draw, especially as with Unicode people in Japan can, and do, use characters outside that set, but it does make the task of database management much more manageable.
Thank you very much Jim. It now makes sense for 戋 to never appear in Kanjidic2.
So, Andrej, what now? If you wish to attach tags to that particular character, I would need to create a dummy Kanjidic2 entry, which will only contain given kanji and no other information - no onyomi, kunyomi, readings,SKIP nor any other information. I can imagine this for users to be very confusing...
I tried to do just that, and it seems to be working. I cannot do this for the マ character though, because it is actually a katakana letter, not a kanji. However, this should work for all other parts.
Fixed in 3.39.1
