-**   isalpha()                        0x02

-**   toupper()                        0x20
-**   SQLite identifier character      0x40
-**
-** Bit 0x20 is set if the mapped character requires translation to upper
-** case. i.e. if the character is a lower-case ASCII character.
-** If x is a lower-case ASCII character, then its upper-case equivalent
-** is (x - 0x20). Therefore toupper() can be implemented as:
-**
-**   (x & ~(map[x]&0x20))
-**
-** Standard function tolower() is implemented using the sqlite3UpperToLower[]
-** array. tolower() is used more often than toupper() by SQLite.
-**
-** Bit 0x40 is set if the character non-alphanumeric and can be used in an 
-** SQLite identifier.  Identifiers are alphanumerics, "_", "$", and any
-** non-ASCII UTF character. Hence the test for whether or not a character is
-** part of an identifier is 0x46.
-**
-** SQLite's versions are identical to the standard versions assuming a
-** locale of "C". They are implemented as macros in sqliteInt.h.
