Wildcard/Regex search for [A-Z without Q] in Microsoft Word

Question

Is there an expression for excluding a single character from a character range in the (arguably somewhat peculiar) Regex syntax of Microsoft Word?

These don't seem to work:

[A-Z\Q]
[A-Z|Q]
[A-Z^Q]
[A-Z!Q]

This question is not a duplicate question to that one, since the latter is about Java, and since Word has its own Regex implementation. The fact that some answers over there might be applicable for Word doesn't change that.
