I want to know the answer to the following question:
What may render certain names in katakana instead of kanji?
All the background I'm provided with is that "Newspapers have dealt with this problem in varying ways, including using software to combine two existing, similar characters, including a picture of the personality, or, especially as is the case with Yu Shyi-kun, simply substituting a homophone for the rare character in the hope that the reader would be able to make the correct inference.". Is that enough to answer the question?
