However, for the sake of consistency and standardization, the CPC seeks to limit the use of such polysyllabic characters in public writing to ensure that every character only has one syllable. Conversely, with the fusion of the diminutive "-er" suffix in Mandarin, some monosyllabic words may even be written with two characters, as in "huār" "flower", which was formerly disyllabic. In most other languages that use the Chinese family of scripts, notably Korean, Vietnamese, and Zhuang, Chinese characters are typically monosyllabic, but in Japanese a single character is generally used to represent a borrowed monosyllabic Chinese morpheme (the "on'yomi"), a polysyllabic native Japanese morpheme (the "kun'yomi"), or even (in rare cases) a foreign loanword. These uses are completely standard and unexceptional. Often a character not commonly used (a "rare" or "variant" character) will appear in a personal or place name in Chinese, Japanese, Korean, and Vietnamese (see Chinese name, Japanese name, Korean name, and Vietnamese name, respectively). This has caused problems as many computer encoding systems include only the most common characters and exclude the less often used characters. This is especially a problem for personal names which often contain rare or classical, antiquated characters. One man who has encountered this problem is Taiwanese politician Yu Shyi-kun, due to the rarity of the last character in his name. 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. Taiwanese political posters, movie posters etc. will often add the bopomofo phonetic symbols next to such a character. Japanese newspapers may render such names and words in katakana instead, and it is accepted practice for people to write names for which they are unsure of the correct kanji in katakana instead. There are also some extremely complex characters which have understandably become rather rare. According to Joël Bellassen (1989), the most complex Chinese character is / (U+2A6A5) "zhé" , meaning "verbose" and containing sixty-four strokes; this character fell from use around the 5th century.
