Power Query Text Combine separator

Hi, in MS docs Csv.Document a seperator is used in Text .combine, "#(cr)#(If)"

I think these are ASCII or Unicode but I can't any help in how to use them or what each means. Also what is annoying
is that whenever I type it in I get ; invalid literal, but if I copy past from stie it works, and I can't see any difference.

So I would really just like direction to more information on this,

Richard.

Carriage Return CR \r ASCII code 13
Line Feed LF \n ASCII code 10

Thanks,

Richard.

Tks for the feedback, glad to help.
