not every text file a text file?

[Friedrich F. Grohmann]

I've been trying to work with the "read from file" command (Rev 2.1.2 on 
a G4 PowerBook with OS 10.3.2). The file involved was produced in Nisus 
Writer Express and saved as text. Nothing happened despite all attempts 
to "improve" the script including "get URL". I finally copied the text 
into a TextEdit file and it worked. 

Does this mean that not all text files will be recognized by Rev? Why 
TextEdit but not NWE? 

Slightly baffled,
Fritz
