Why is there a mistake in the wix project?

Question

I am using the Wix 3.8 toolkit and I am trying to create an msi project. During build I have an error similar to this:

Severity Code Description Project File Line Error '.', hexadecimal value 0x00, is an invalid character. Analyzer light.exe 0 

Has anyone encountered such a problem? Any help would be appreciated! I am new to this area ... Here is the source code:

There is an open error report in the WiX issue tracking system that indicates that the error is related to your RTF file ending with a null character.

I would check if your license.rtf ends with the null end and then truncates this character from the file (or create a new RTF file without a null value)
