An interesting question that comes up periodically when people look at Unicode....
As is true of other cases, this question has a true 'drive on a parkway, but park on a driveway' feel to it.
But the truth is that there are many Unicode characters with names like MODIFIER LETTER ______, and while some of them have a general category of Lm (Letter, Modifier), some of them do not. Many of them have a general category of Sk (Symbol. Modifier), instead.
The difference between the two general category values? Well, the principal difference is whether they can be used in identifiers -- Sk characters cannot, and Lm characters can. This is actually the main reason that Sk was added to Unicode!
I will be talking about some of these in upcoming posts, in the context of every Unicode character having a story....
