I recently organized a note on the currency symbols of various countries and found that this thing seems simple, but actually has quite a few details. Especially for common symbols like the euro and dollar signs, it's easy to get confused.

The most interesting is the ￥ symbol, which represents the Japanese Yen in Japan and the Chinese Renminbi in China. The two countries actually use the same symbol. So you need to be clear: either write CNY￥100 to indicate Chinese Renminbi, or JPY￥100 for Japanese Yen. And the $ symbol is even more outrageous, used in over 30 countries worldwide, including the US dollar, Canadian dollar, Hong Kong dollar, New Taiwan dollar, and Australian dollar—all with the same $ sign, making it the "public face" of symbols.

Speaking of the euro symbol €, it’s quite unique and used very frequently in international transactions. Pairing it with the dollar as EUR/USD is a common sight in the forex market. But if you ask me how to type these symbols on a keyboard, Mac and Windows each have their own shortcuts. For example, on Mac, pressing Shift+Option+2 will produce the euro symbol; on Windows, pressing Alt+E works. The ￥ and £ symbols also have their own shortcut keys.

In the forex market, there's also a concept called currency pairs, which compare the exchange rate between two currencies, like EUR/USD representing the euro against the dollar. The first is the base currency, and the second is the quote currency. This is different from a single currency symbol; symbols only represent one currency, while currency pairs show the exchange relationship between two currencies.

I’ve organized the entire table, covering currencies from the Americas like the US dollar and Canadian dollar, to Asia’s Renminbi, Yen, and Korean Won, to Europe’s Pound and Euro symbols, and also various currencies from the Middle East and Africa. Each has its corresponding code and symbol. Sometimes, when doing international transactions or viewing forex quotes, these basic pieces of knowledge are quite useful.
