Description

This could be reproduce in Spreadsheet demo site.

When I enter some multi-byte characters in a cell, a first character is accepted as single byte character just like attached file.
(In Japanese, type "a" when I want to enter "あ". In attached file case, it should be "あ" not "aあ". )

This problem was also seen in the initial google spreadsheet.
I strongly hope this could be fixed because this is Pro tool.

Research direction

Start by reproducing the issue in the linked Spreadsheet demo using Chrome or Edge and entering a Japanese multi-byte character into a cell. Compare the first-character behavior with the expected single character, then trace the spreadsheet cell-editing entry point and add coverage for the reproduction before confirming that the unwanted leading character is gone.
