Similarly, the following pattern also doesn't match.

string pattern = @"([\p{IsBasicLatin}-[\p{Cc}]])+";

It is actually used in OOXML RELAX NG grammar. It is almost just as a note, the
following pattern and the target must match:

string pattern =
@"(((([\p{IsBasicLatin}-[\p{Cc}\x127\(\)<>@,;:\\""/\[\]\?=\{\}\s\t]])+))/((([\p{IsBasicLatin}-[\p{Cc}\x127\(\)<>@,;:\\""/\[\]\?=\{\}\s\t]])+))((\s+)*;(\s+)*(((([\p{IsBasicLatin}-[\p{Cc}\x127\(\)<>@,;:\\""/\[\]\?=\{\}\s\t]])+))=((([\p{IsBasicLatin}-[\p{Cc}\x127\(\)<>@,;:\\""/\[\]\?=\{\}\s\t]])+)|(""(([[\x80-\xFF]\p{IsBasicLatin}-[\p{Cc}\x127""\n\r]]|(\s+))|(\\[\p{IsBasicLatin}]))*""))))*)";
string target =
"application/vnd.openxmlformatsofficedocument.wordprocessingml.footnotes+xml";

This might expose other regex issues, but this bug blocks further research so
far.
