Note that when Whitespace source code is displayed in some browsers, the horizontal spacing produced by a tab character is not fixed, but depends on its ___location in the text relative to the next [[Tab key#HTML|horizontal tab stop]]. Depending on the software, tab characters may also get replaced by the corresponding variable number of space characters.
