Then, read trims white space when assigning the fields to one or more variables. However, $(line) costs a fork and exec, while read is ksh builtin and buffered. Apparently, it only affects edge whitespace:

Hello!
I am not familiar with UNIX and I have this problem:
I need to move files from a UNIX machine to a PC. UNIX file names contain ":" as special character which is not recognized in a PC.
