I have strings that contain a space in an unexpected location.  The
intended string is:
        “STRING 01.  Remainder of the string"
However, variants are:
        “STR ING 01.  Remainder of the string"
        “STRIN G 01.  Remainder of the string"

I would like a general approach to deleting a space, but only if it
appears before the period.  Any suggestions on a regular expression
for this?

You aren't deleting the space before 0? Is that in the requirement?
