wp_mail_charset WordPress Filter Hook
This hook allows you to change the charset used for sending emails through the wp_mail function. By default, the charset is set to UTF-8, but you can change it to something else by using this hook.
apply_filters( 'wp_mail_charset', string $charset ) #
Filters the default wp_mail() charset.
Parameters
- $charset
(string)Default email charset.
More Information
- The default character encoding for wp_mail() is UTF-8. The character encoding can be changed using the
wp_mail_charsetfilter. - While the average user is unlikely to need to change the default character encoding for email, users who need to send email in different languages may find this filter useful.
- UTF-8 is still the recommended default character encoding to use since it’s backward compatible with ASCII and can represent nearly all languages. As a result, UTF-8 is the most ubiquitous character encoding being used on the web. Users/developers typically do not need to change the character encoding in order to read/write foreign langauges.
- As of Version 3.5, WordPress character encoding is no longer configurable from the Administration Panel and defaults to UTF-8.
