Example 1. convmap example
$convmap = array ( int start_code1, int end_code1, int offset1, int mask1, int start_code2, int end_code2, int offset2, int mask2, ........ int start_codeN, int end_codeN, int offsetN, int maskN ); // Specify Unicode value for start_codeN and end_codeN // Add offsetN to value and take bit-wise 'AND' with maskN, // then convert value to numeric string reference.
