For the AS/400, but I think probably applicable or 99% applicable to z/OS.
Note the exception list at the top.

I have used this list when I needed to design a token that could be e-mailed
to a customer and produce predictable code points on the z.

I would never use the nationals because of their instability.  Which of the
following are stable across code pages?
, comma
. period
( left parentheses
) right parentheses
* asterisk
+ plus sign
- minus sign or hyphen
= equal sign
& ampersand
% percent sign
_ underscore
/ slash
< less than sign
> greater than sign
: colon
; semi-colon
