Additional notes

 * This API is primarily intended for changing options which are registered by MediaWiki core or extensions and available on Special:Preferences.
 * You can also use the API to set arbitrary user options that can be used by user scripts or external editors. These options must begin with the prefix.
 * There is currently no limit on the number of user options you can set at once. You can store data within a user option by encoding it as a  string.
 * Providing only names of options without equal sign results in resetting them (e.g. ). In the case of an arbitrary   key/value pair, the resetting results in its deletion.
 * The  parameter cannot be used to set a value which contains a pipe character , as it is used by the API to separate options. If you need to set such a value (e.g., a user signature) use an   &   pair.
 * The following limits apply to all user options:
 * The byte length of the key must be <= 255.
 * The byte length of the value must be <= 65535.
 * The key must consist only of ASCII letters, numbers, hyphens and underscores (a-z, A-Z, 0-9, _, -).
