What version of PHP?

[vbgamer45]

I tested on PHP 7.1.x
elkarte was doing this on that line

Code Select Expand


$context['board']['name'] = htmlspecialchars(strtr($context['board']['name'], array('&' => '&')), ENT_COMPAT, 'UTF-8');
$context['board']['description'] = un_preparsecode($context['board']['description']);

Let me guess, you're not running UTF-8 (the default for htmlspecialchars since 5.4)

[vbgamer45]

Guess not in my php.ini the default is empty it is commented out

; PHP's default character set is set to empty.
; http://php.net/default-charset
;default_charset = "UTF-8"

what about your database?

Confirmed.  Issue is specifically with 4-byte characters, e.g.: 𣎏 世 咹 水 晶 𦓡 空 𣎏 害 咦

Issue also exists with category names, but at least you can update & fix the categories.  You cannot fix the board names. 

Logged as #75

2.1 works properly.

[Arantor]

This is because it doesn't use $smcFunc's version of htmlspecialchars that dos multibyte fixing.

[shawnb61]

Yup.
