High Quality Content by WIKIPEDIA articles! In relation to the Japanese language and computers many adaptation issues arise, some unique to Japanese and others common to languages which have a very large number of characters. The number of characters needed in order to write English is very small, and thus it is possible to use only one byte to encode one English character. However, the number of characters in Japanese is much more than 256, and hence Japanese cannot be encoded using only one byte, and Japanese is thus encoded using two or more bytes, in a so-called "double byte" or "multi-byte" encoding. Some problems relate to transliteration and romanization, some to character encoding, and some to the input of Japanese text.
