"Including Macros in EmEditor Causes an ""Incorrect Characters"" Error"

If you just stick the macro together, it will work as usual.

#include "Macro.jsee to include"

The previous experiment was to see if multiple simple macros would work with inclusion.
What do you mean by incorrect characters?

I saw EmEditor's help, but the search didn't get a hit.What is the cause of this?
Thank you for your cooperation.
