    You must use the PHP function mb_strlen to get username length for UTF8 characters and not strlen as UTF8 use 2 bytes for local characters.

    strlen will return the result 6 characters for this string ???
    and mb_string will return 3.

    /wpum-username-length/includes/actions.php

    lines 28/30

    		$username   = $values['register']['username'];
		$min_length = wpum_get_option( 'username_min_length' );
		$max_length = wpum_get_option( 'username_max_length' );
		$length     = mb_strlen( $username );

    Plugin: WPUM Username Length version 2.0.0

    Hi @missveronicatv

    Thanks for pointing this out, I’ll release a proper fix into the next update, also note that mb_strlen isn’t automatically installed on all servers that come with php.
