What's the contents of the original file? The output will depend on the coding of the original file. Were all the characters in the original file standard ones ( ASCII )? Anyway, read carefully the documentation of textread:
doc textread
You'll be tipped with several examples worth testing.

If you are seeing those particular characters then your file is UTF encoded. I do not recall at the moment whether it is UTF-8 or UTF-16 that uses that exact sequence.
Remember that %s format reads a string at a time, and strings are terminated by whitespace. Are you trying to split it up into words or split it up into lines?
filename='E:\outpo.txt';
x = regexp( fileread(filename), '\n', 'split'); %read it and break it into lines.
