    [NTOS] Just go ahead and allow printing all the printable ASCII characters in
ExpTagAllowPrint().
    As documented in
https://docs.microsoft.com/fr-fr/windows-hardware/drivers/ddi/wdm/nf-wdm-ex…
    pool tag "characters" must be a value in the range 0x20 (space) to 0x7E
(tilde),
    which happen indeed to be the range of printable (non-extended) ASCII characters.
    (The display problem was originally caught while attempting to display
    the pool tag 0x3a306847 corresponding to 'Gh0:', a win32ss GDIOBJ pool tag
    encoded with macro GDIOBJ_POOL_TAG().)
