LDAP Decision Node in authentication tree can't work with UTF Character

Hi Guys. I am using LDAP Decision Node for my authentication tree, it work fine will all normal case. But when my password has non english characters. It cannot authenticate and return 401 at AM.
I’ve try with this document: ForgeRock Access Management 7.1.2 > Authentication and Single Sign-On Guide > Logging in to AM Using REST but still not work.
Can someone facing with this issue? How can I work arround in this case.
