Jboss Form Auth fails when using password with utf8 characters

[vanduc1102]

I am using both Jboss 7.1.1 and Wildfly10

for my application, I am using authentication by LDAP

And I have issue with utf-8 accents in password

for example, username with password contained "é" can not login to the application

with Wildfly10, I found a solution here

Wildfly Form Auth fails when using special characters

But I can not find the same config for Jboss.
