I supposed that the control character class of tcl re would contain
unicodes 0-1f,7f-9F
What is wrong here:
% regexp {^[[:cntrl:]]*$} \x01
0
...
% regexp {^[[:cntrl:]]*$} \x1f
0
% regexp {^[[:cntrl:]]*$} \x7f
1
...
% regexp {^[[:cntrl:]]*$} \x9f
1
So, \u0000 - \u001f is not in this character class ?
I feal I am really missing something...
I tried with tcl8.4,8.5,8.6, all like that...
This says, it should be the upper range
http://en.wikipedia.org/wiki/Unicode_control_characters
This says, it is only 0-1f:

Thank you for any insight...
