I have not checked all your examples, but
I can suggest lines of attack.
First line of attack: try "\'", not "'".
Second, reach for SMCL.
. di "{c 39}whatever"
Third, use -char()-.
. di "`=char(39)'whatever"
Agreed: these are all more or less painful.
In a program or do file, I'd put ` and then
do a conditional search and replace with
a decent text editor.
