in thread Removing Non-Ascii chars from text file

Correct. ASCII "includes definitions for 128 characters: 33 are non-printing control characters... and 95 printable characters..."
See this scanned copy of the original "American Standard Code for Information Interchange (ASCII)" from 1963, the 5th page in particular. This definition is also enshrined in Internet RFC 20.
