Synchronize Tool not working?

Dear support,
I'm trying to use the synchronize tool to compare 2 folders as below.
The file names are Korean, but they both have the same name and the file size is equivalent(They have the same bite size).
However, the result shows as if the two files are different.
Does the synchronize tool not support non-english languages such as Korean?

The filenames are matching so it won’t be those causing problems.

If you add the Size (Bytes) column, are the sizes exactly the same?
