ENTITY

Specifies a substitution character when input character encoding is invalid or character code does not exist in output character encoding. Invalid characters may be substituted "none" (no output), string or int value (Unicode character code value).

This setting affects mb_convert_encoding, mb_convert_variables, mb_output_handler, mb_scrub, and mb_send_mail.

ENTITY

substitute_character
Specify the Unicode value as an int, or as one of the following strings:

• "none": no output

• "long": Output character code value (Example: U+3000, JIS+7E7E)

• "entity": Output character entity (Example: ENTITY#x200;)

ENTITY

If substitute_character is set, it returns ENTITY for success, otherwise returns ENTITY. If substitute_character is not set, it returns the current setting.
