Regex getting converted when checked-in to github

Question

I'm having the regex in one of the file as shown below.

pattern = "^[^,&*\n\t\r]*"

But when i check-in that to github, it's getting converted to invalid characters as shown in the below image.

I have added the .gitattributes as shown below. Still getting this error. Any help would be appreciated.

* text=auto
*.proto text

Answer 1

I suggest using the hex notation for each of the whitespace chars:

pattern = "^[^,&*\\x0A\\x0D\\x09]*"

This way, the pattern will be passed as ^[^,&*\x0A\x0D\x09]* text and \xNN regex escapes will be parsed by the regex engine itself, not by the language engine.
