Thanks, is there full code for this somewhere?
For the specific case of Sep I doubt this will be faster given the mask for each special character is used too. Eg mask for column separator is used to check if only separators and quick readout of those which is why Sep is fast for this common case.

I definitely did today when I found out that to change the name of column of a 2GB csv file that is in the first line of the file, the file was read into memory as a single string and then Replace(..) called on the entire file... 😅 It's a good thing #dotnet is damn fast!
