推荐答案

您需要做三件事：

1. 请确保您重新接收数据作为UTF-8数据。对于MySQL，在选择记录前先查询 SET NAMES'utf8'。


2. 请确保在处理时使用的是UTF-8兼容函数


3. 请确保将输出编码设置为UTF-8。对于HTML，这可以通过将 Content-type HTTP标头设置为（例如） text / html来完成。 charset = utf-8 。

1. Make sure you're receiving the data as UTF-8 data. For MySQL, query SET NAMES 'utf8' before selecting records.
2. Make sure you're using UTF-8 compatible functions when dealing with UTF-8 strings.
3. Make sure you're setting the output encoding as UTF-8. For HTML, this can be done by setting the Content-type HTTP header to (e.g.) text/html; charset=utf-8.

当然，将 UTF-8替换为所需的编码支持您需要的字符。无需更改数据库表（可能会提高性能）。如果您决定使用UTF-16或其他（大多）不兼容ASCII的内容，则可能需要更改HTML模板等。

Of course, replace "UTF-8" with whatever encoding you want which supports the characters you need. There's no need to change the database tables (except for possible performance gains). You may need to change HTML templates, etc. if you decide on UTF-16 or something else which isn't (mostly) ASCII-compatible.
