How do i install Myanmar zawgyi font in Marshmallow samsung s7

[AC Question]

As marshmallow doesn't allow third party font therefore I can't use the myanmar zawgyi font in my Samsung s7 anymore. Is there anyway I can solve this? I have asked samsung about this issue and the staff reply the problem lies with android and not with samsung I received this reply after i waited one-year patiently. I asked samsung the reason being the phones which are sold in Myanmar and Thailand ,myanmar zawgyi fonto was installed upon purchasing.hope somebody can help to solve this
