You need to quote "stringFromTheClipboard" -- the shell is seeing each space-separated bit of the original string as a separate parameter, and echo(1) prints exactly one space between them. Do this instead:
set fixedName to do shell script "echo " & quoted form of stringFromTheClipboard & ...
Using "quoted form" is a almost always a good idea when building a "do shell script" command from a variable.
