Can't speak for IN China, but internationally the Yen and the Yuan have different symbols: the Yen gets 1 cross-line, the Yuan 2. (And the US dollar gets 2 vertical lines, while all other "dollar" currencies get only 1 -- because the symbol was originally a U superimposed on an S (US - get it) and then they truncated the bottom of the U to get the US dollar symbol ). But when it comes to international business and currency trading, all currencies are marked by 3-letter codes, not symbols: e.g., USD (US Dollars), BPS (British Pounds Sterling), EUR (Euros), JPY (Japanese Yen), etc. See http://en.wikipedia.org/wiki/Currency_codes for a complete list and full description.

Not really an answer, this is thought as a correction of the question, a complement of information and a reply to the first answer from Jack Wallace. Thank you again for answering! I based my question on the following information I found in Wikipedia: 1) "The yen (円, en?) or en is the currency of Japan. It is the third most-traded currency in the foreign exchange market after the United States dollar and the euro. It is also widely used as a reserve currency after the U.S. dollar, the euro and the pound sterling. The ISO 4217 codes for the yen are JPY and 392. The Latinised symbol is ¥ while in Japanese it is also written with the kanji 円." Source and further information: http://en.wikipedia.org/wiki/Yen 2) "The yuan (everyday use: å…ƒ; traditional Chinese: 圓; simplified Chinese: 圆; pinyin: yuán; Wade-Giles: yuen; literally "round") is, in the Chinese language, the base unit of a number of modern Chinese currencies. The same character is used to refer to the cognate currency units of Korea and Japan, and is used to translate the currency unit "dollar"; for example, the US dollar is called Meiyuan (美元), or "American yuan", in Chinese. When used in English in the context of the modern foreign exchange market, the "Yuan" or "Chinese yuan" most commonly refers to the renminbi (CNY)." Source and further information: http://en.wikipedia.org/wiki/Chinese_yuan "The renminbi (simplified Chinese: 人民币; traditional Chinese: 人民幣; pinyin: rénmínbì; literally "people's currency") is the currency of the mainland of the People's Republic of China (PRC).[1], whose principal unit is the yuan (simplified Chinese: å…ƒ or 圆; traditional Chinese: 圓; pinyin: yuán; Wade-Giles: yüan), subdivided into 10 jiao (角), each of 10 fen (分). The renminbi is issued by the People's Bank of China, the monetary authority of the PRC. The ISO 4217 abbreviation is CNY, although also commonly abbreviated as "RMB". The Latinised symbol is ¥." "The word yuan in Chinese literally means round, after the shape of the coins. The Korean and Japanese currency units, won and yen respectively, are cognates of the yuan and have the same Chinese character (hanja/kanji) representation, but in different forms (respectively, 원/圓 and 円/圓), also meaning round in Korean and Japanese." Source and further information: http://en.wikipedia.org/wiki/Renminbi "Hanja is the Korean name for Chinese characters. More specifically, it refers to those Chinese characters borrowed from Chinese and incorporated into the Korean language with Korean phonetics." Source and further information: http://en.wikipedia.org/wiki/Hanja "Kanji (help·info) (漢字, ?) are the Chinese characters that are used in the modern Japanese logographic writing system along with hiragana (平仮名), katakana (片仮名), and the Arabic numerals. The Japanese term kanji (漢字) literally means "Han characters"." Source and further information: http://en.wikipedia.org/wiki/Kanji 3) After reading this again, I realized that this means: - internationally the yuan and the yen have the same Latinized symbol ¥. - in China, the yuan, the yen, the won and the dollar are referred to with the same character (everyday use: å…ƒ; traditional Chinese: 圓; simplified Chinese: 圆) - in Korea and in Japan, they have the same symbol if they use the borrowed Chinese characters (圓), and they have also the same symbol if they use the own character: 원 for won and yuan (and probably yen) in South Korea, 円 for won and yen (and probably won) in Japan. By the way, the currency in North Korea in not transcribed won but wŏn (but seems to have the same sign and symbol otherwise e.g. â‚©) 4) Some fonts are writing the dollar and the yen symbol only with one cross-line: http://www.typofonderie.com/alphabets/view/AngieSans I found an interesting discussion about writing the dollar and the yen symbol with one or two cross-line here: http://www.typophile.com/node/18616 And Wikipedia gives as origin for the double cross-line in the dollar sign the Spanish Coat of Arms: http://en.wikipedia.org/wiki/Dollar_sign#Spanish_Coat_of_Arms
