US ASCII

This is the visible part of the venerable US-ASCII character set. There are 127 characters in the set, 0-31 and 127 are unprintable control characters, 32 (the first one listed here) is a space. Characters 33-126 are printable characters.

These are the only characters allowed to appear in the raw source code. Additionally, "&" may not appear alone, it must always be an entity (&), even if present in a URI. If "&", "<" or ">" need to appear as visible characters on the finished web page then these too need to be encoded.
