Instead of an expected character, a sequence of Latin characters is shown, typically starting with Ã or Â. For example, instead of "è" these characters occur: "Ã¨".
A common problem is for characters encoded as UTF-8 to have their individual bytes interpreted as ISO-8859-1 or Windows-1252. For example:
A character such as è (e-Grave, U+00E8) consists of two bytes in UTF-8: 0xC3 and 0xA8. If each of these bytes are treated as either ISO-8859-1 or Wiindows-1252 code points, then the displayed characters will be Ã and ¨.
|Character||UTF-8 Bytes||Bytes viewed in Latin-1|
|è||0xC3, 0xA8||Ã, ¨|
You can use the Encoding Debug Table to look up any erroneous sequence of Latin characters and find out the UTF-8 character that it corresponds to and that generated it.
