Bug Summary and Steps to Reproduce

Bug Summary:
I found that when Chinese characters appear in the middle of an ifdef macro, the code parsing will be incorrect.
The below screenshots show the issue. A very strange problem.
The first image is correct, while the parsing in the second and third images is incorrect.

By the way, I tested version 1.21.6 of the C/C++ extension and didn't encounter this issue.
