When loading textfiles rapid miner is introducing spaces and special chars

Hi,

I am trying to do a very simple task of loading text files using the operator "Process documents from files" . After loading I see that there are spaces between each character in the file and also a special character (ÿþ) in the beginning of every file .

example :

b a l a n c e s h e e t

I am really stuck and would appreciate any help.
I chose the regular options while loading files adn dint see this problem in any of the tutorials and is happening to me

adding to my question -- I notice this does not happen to all files but only to the ones I exported from nvivo. But I exported as normal text files and look normal to me but turn up wierd in Rapidminer. Please help.

Hello,
Are you sure those second characters are spaces and not with code 0? (Spaces have code 32.) It seems -assuming those are 0s- that the nvivo files are saved as UTF-16 with byte order mark set. (I guess RM do not try to use the encoding specified by BOMs.)
Cheers, gabor

thanks a lot for the reply. They look like spaces to me . I am not sure if they are anything else. In notepad I see them as a white space.

Di you try to change the encoding parameter of Process Documents from Files?
