æå¹ï¼ Something weird appears in an Android Excel document comment.

It might seem to be a tricky question. Typing other specific characters (maybe CJK and symbols) in a comment of Excel of an Android Phone garbled. This situation only happens in several Android Phones, and it's quite hard to tell which of them. Only the comments went wrong. Others like user interface, things in cells or VBA are not affected using the language as same as the comment.

Meanwhile doing the same thing in computer or opening the same file which went wrong on Android phone, this problem dissipates. This problem does not occur when opening it in OneDrive. How could things went wrong only in some Android Devices.
