How to solve select box problem with MW WP Form

When using the select box in MW WP Form, there is a problem that “Please select” is displayed even if you select a choice on your iPhone. This is because when characters are copied from a PDF or other source, the UTF8-MAC causes characters such as muddy marks to be broken up.

To resolve this, use the nkf command to convert the character encoding. The specific command is as follows

nkf -w --ic=UTF8-MAC --overwrite test.text

This command will convert the encoding of the file in question to the normal UTF-8, so that it can be correctly displayed and selected in MW WP Form.
