public static byte _isLike(long packAddr, LikePattern pattern) {

    UTF8String original = pattern.original;
    int bytes = original.numBytes();
    Object valueBase = original.getBaseObject();
    long valueOffset = original.getBaseOffset();
    int indexSize = bytes < POSISTIONS ? bytes : POSISTIONS;

    for (int pos = 0; pos < indexSize; pos++) {
        byte c = Platform.getByte(valueBase, valueOffset + pos);
        // The ESCAPE_CHARACTOR case can be optimized. But I'm too lazy...
        if (c == '%' || c == ESCAPE_CHARACTOR) {
            break;
        }
        if (c != '_' && !isSet(packAddr, c, pos)) {
