Manual:$wgLegalTitleChars/zh

详情
This is a regex character class (i.e. a list of characters in a format suitable for a regular expression) that you want MediaWiki to allow in page titles despite being in the list of illegal characters.

The list of illegal characters is as follows:, non-printable characters 0 through 31, and 'delete' character 127.

存在问题的字符
如果启用了以下标点符号可能会导致问题：

在极少数情况下，您可能希望删除+以与旧链接兼容.
 *   - 这些是链接和模板语法所必需的，切勿启用它们.
 *   - 这些会导致HTML转义问题，请不要使用.
 *   - 请求的重写规则（rewrite）的路径存在一些小问题，请参见下文. 包含在默认的允许列表中.
 *   - 在apache中请求的重写规则的路径无法正常运行. 自MediaWiki 1.8.0版本开始被包含于默认的允许列表中.
 *   - 对于PATH_INFO重写的路径无法正常运行. 被包含于默认的允许列表中.

最后三个标点问题可以通过使用别名（alias）而不是重写（rewrite）规则来避免.

The problem with % is that when using a path to query rewrite rule, URLs are double-unescaped: once by Apache's path conversion code, and again by PHP. So %253F, for example, becomes "?". Our code does not double-escape to compensate for this, indeed double escaping would break if the double-escaped title was passed in the query string rather than the path. This is a minor security issue because articles can be created such that they are hard to view or edit.

Theoretically 0x80-0x9F of ISO 8859-1 should be disallowed, but this breaks interlanguage links and so they are included in the allowed list by default.
