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. 


 Text.Combine(  { "A , B" , "1, firstline", "2 , secondline"}, "#(cr)#(lf)") 


 Csv.Document(    Text.Combine(  { "A , B" , "1, firstline", "2 , secondline"}, "#(cr)#(lf)"), 2 , ",")
So I would really just like direction to more information on this,

Richard.
