The example that I have is from South Africa. Chartered accountants here abbreviate their titles in emails to:
This is meant to abbreviate "Chartered Accountant (South Africa)". I feel, however, that this may be a mistake that is propagated by a precedent set by other accountants.
Is it not more correct to use a space?
Orthographically, this seems more consistent to me.
There is no question about spaces in the original phrase: "Chartered Accountant (South Africa)". Instead, the question is about whether parentheses need spaces when the whole phrase is abbreviated.
The general question is: How does a bracket, preceded by a space, compile to an abbreviation? When the phrase in question refers to a named entity it seems like common courtesy is to use whichever style the entity itself prefers.
