3813031 - Why is our 'no special characters' field validation rule triggering for all text?

I moved the validation expression, that was working in test, to production and it failed completely. Can you please look into this and figure out why production is not accepting the same expression code that works in the test entity?
It is also possible that you are getting an error stating that you should not be using special characters for a certain field.
 
The expression is:
^[^<>`~!/@\#}$%:;)(_^{&*=|'+]+$

This should block everything except the below special characters, it allows for spaces, commas and periods.
-, ?, ", [, ], \

Field validation is triggering for all text instead of for certain special characters. , KBA , CON-EXP-ADM-FOF , Forms and Fields , Problem
