The SQLite library may be compiled in either ISO-8859-1 or UTF-8 compatible modes. This function allows you to determine which encoding scheme is used by your version of the library.
| 警告 |
The default PHP distribution builds libsqlite in ISO-8859-1 encoding mode. However, this is a misnomer; rather than handling ISO-8859-1, it operates according to your current locale settings for string comparisons and sort ordering. So, rather than ISO-8859-1, you should think of it as being '8-bit' instead. |
When compiled with UTF-8 support, sqlite handles encoding and decoding of UTF-8 multi-byte character sequences, but does not yet do a complete job when working with the data (no normalization is performed for example), and some comparison operations may still not be carried out correctly.
| 警告 |
It is not recommended that you use PHP in a web-server configuration with a version of the SQLite library compiled with UTF-8 support, since libsqlite will abort the process if it detects a problem with the UTF-8 encoding. |
