multibyte function to display truncated admin configuration values

[gernot]

Zen Cart 1.5.6c, MariaDB 10.3.20, PHP 7.3.11

Again, a quick fix for an issue of incorrectly-trunctated fields, this time in the configuration table displays. It occurs for me for Japanese configuration items like store address. In ADMIN/configuration.php, change the display of the value to use mb_substr instead of substr:

<td class="dataTableContent"><?php
 $setting = htmlspecialchars($cfgValue, ENT_COMPAT, CHARSET, TRUE);
 if (strlen($setting) > 40) {
   echo mb_substr($setting,0, 35) . "...";
 } else {
   echo $setting;
 }
?></td>

Maybe this and the related fix for sidebox display trunctions issues here
