Actually, no. Not according to a couple dictionaries I glanced at,
and OpenSolaris:
509 $ ls -1
castor
Castor
castor bean
510 $
What does Linux do?
The technique appears to be: First sort as if entirely case-insensitive;
only then resolve any ties by considering the case of the characters.
Which is why I suggested keeping all alphabetic characters in a single
case, followed by a bitmap identifying the case of the characters.
Case-insensitive lookup would ignore the bitmap; case sensitive would
consider it.
