** The following 256 byte lookup table is used to support SQLites built-in
** equivalents to the following standard library functions:
**
** isspace() 0x01
** isalnum() 0x02
** isdigit() 0x04
** isxdigit() 0x08
** toupper() 0x20
**
** Bit 0x20 is set if the mapped character requires translation to upper
** case. i.e. if the character is a lower-case ASCII character.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.
**
** SQLite's versions are identical to the standard versions assuming a
** locale of "C". They are implemented as macros in sqliteInt.h.
