ASCII is 7 bits, so it's not a problem with your table. To understand the
exlusion of these characters, you need to realise that the
character set is also used to interpret double-click (i.e. select
"words"), and need to know how the ISO 8859-1 character set ("Latin 1"; see
latin1(7)) is constructed.
ISO 8859-1 is perhaps the de facto ASCII replacement. It is a proper
superset of ASCII, and is sufficient for most west European languages.
In 0-127, it is ASCII. 128-159 are undefined (so that transfers that
accidently strip the 8th bit do not introduce control characters). 160-191
are non-word characters (e.g. copyright sign, currency signs etc). 192-255
are accented characters and characters that are only used in few languages
(e.g. the ae ligature), with the exception of 215 (multiplication sign) and
247 (division sign).

This would make the double click behaviour useless, as it would do the same
as triple click: select whole lines.
