Unless you have a use case where people will be opening the files you create with notepad, this should work fine. For example, the code point number of the euro sign in Windows code page is For example, to select an element in HTML with the class name "", you would write the following. An example is the strlen function that will return the number of bytes rather than the number of characters. The following all show valid ways of escaping a sequence of characters, such as those in the sequence of Egyptian hieroglyphs , meaning 'voice'. First, we set the encoding type for the column back to latin1, thereby removing the double encoding: e. Wrap-up Although it can be somewhat tedious, taking the time to go through these steps to systematically address your MySQL and PHP UTF-8 data encoding issues can ultimately save you a great deal of time and grief. On a previous job , we began running into data encoding issues when displaying bios of artists from all over the world. The x indicates that what follows is a hexadecimal number representing the code point value of a Unicode character. In MySQL 5.
Source code and resource files One other thing to remember and verify is that your source code files, resources files, and so on, are all being saved properly with UTF-8 data encoding. So if the class name you want to refer to happens to begin with a digit you will need to escape it.
See, however, the next subsection for issues related to using digits at the start of an identifier. See the test pages. The following all show valid ways of escaping a sequence of characters, such as those in the sequence of Egyptian hieroglyphsmeaning 'voice'.
Since non-ASCII characters are multi-byte by design, we can find them by comparing the byte length to the character length i.
ArtistName varchar character set latin1; Note: Be sure to use the correct field type for your table. Remember, though, that the strings you provide to these functions must themselves be properly encoded.
There is no need to also escape the '23' part of the identifier, since digits are allowed after the first position.

Using the semicolon also avoids the potential problem of the end of the escape becoming undetectable when the escape is embedded in text. What does UTF-8 stand for? If you have ever opened a file with notepad on windows and found that it appears that everything is on one line, but then open it in another editor to find that the lines appear, the reason for that is that the file is delimited with only LF Chr 10 and not CRLF. This is a very different type of escape. UTF-8 is a variable-width encoding that can represent every character in the Unicode character set. Unless you have a use case where people will be opening the files you create with notepad, this should work fine. There is no need to also escape the '23' part of the identifier, since digits are allowed after the first position. I tend to use only Chr 10 because it takes less space. Escapes start with a backslash followed by the hexadecimal number that represents the character's hexadecimal Unicode code point value.
