Excel Files with Multibyte Characters in Chat Attachment Tool

Hi team, I’d like to confirm the current limitations of the Chat Attachment Tool in Fusion AI Agent Studio.

Is my understanding correct that the tool currently does not support reading Excel files containing multibyte characters, such as Japanese text?

I assume this may also be related to character encoding, as Japanese text may use encodings such as Shift_JIS (SJIS).

Thanks in advance for confirming.
