To my surprise - although MS based Basic interpreters I know of do not -
you are right. The reason could be that Color BASIC does not allow to
generate characters of code >= 128. I could verify this by poking the
token code into the Basic program which is expanded by LIST later on.

But I found another case where a special handling maybe needed:

A comment which is introduced with a tick (') is represented in binary
by $3A $83. The tokenizer implicitly inserts a ":" before the '-Token
and LIST suppresses this ":" ...
However, the output is not wrong if "'" would be shown as ":'". The
Basic code remains valid, but successive conversions back and forth
would lead to a growth of ":". ;)
