| 68 ** isdigit() 0x04 | |

| 71 ** toupper() 0x20 | |
| 72 ** SQLite identifier character 0x40 | |
| 73 ** | |
| 74 ** Bit 0x20 is set if the mapped character requires translation to upper | |
| 75 ** case. i.e. if the character is a lower-case ASCII character. | |
| 76 ** If x is a lower-case ASCII character, then its upper-case equivalent | |
| 77 ** is (x - 0x20). Therefore toupper() can be implemented as: | |

| 79 ** (x & ~(map[x]&0x20)) | |
| 80 ** | |
| 81 ** Standard function tolower() is implemented using the sqlite3UpperToLower[] | |
| 82 ** array. tolower() is used more often than toupper() by SQLite. | |
| 83 ** | |
| 84 ** Bit 0x40 is set if the character non-alphanumeric and can be used in an | |
| 85 ** SQLite identifier. Identifiers are alphanumerics, "_", "$", and any | |
| 86 ** non-ASCII UTF character. Hence the test for whether or not a character is | |
| 87 ** part of an identifier is 0x46. | |
