Foreign characters (Chinese/Japanese) intermittently getting missed while saving the comment.

We are noticing intermittently chinese/japanese characters are getting missed while the comment is saved. Partially the comment is saving without any issue but some part of the chinese and japanese characters are missed.

Attaching screen capture of the issue for more clarity.
