I disagree.  Blanks _do_ have a value, they are part of the string.

The only character that should not be in the output is the separator. 
  All other characters should still be in the output strings.

If the space characters are not wanted in your application, then use 
Trim() to remove them.  Other people will want the spaces - I 
certainly do in some places.  And when I don't want leading/trailing 
spaces, I use trim().

Try split() in other languages - awk, VB, or strtok() in C.  They all 
keep the space characters in the output strings when the separator is 
a single character (but not a space char - this tends to be special).
