Depends on the Kanjis. I used to work for a company doing Japanese handwriting recognition, and we would sometimes get request "can you support kanjis not in unicode" and "lost" contracts because we could not. This is especially the case for rare Kanji for family names, etc. I still have no idea how those customers actually handle those kanjis in their systems, must be fun.
