![]() ![]() So, here we have to make a logical OR with both 0xc3 and 0xb1 HIGH nibble,Ī nibble is a half byte (4 bits), so we have to make a logical OR betweenġ100 (0xc) and 1011 (0xb), we going to get this: 1111 (0xf), then we have to makeĪ logical AND between both LOW nibble, 0011 (0x3) and 0001 (0x1), we going to get ![]() Logical OR ("|" or "pipe") and logical AND ("&" or "and person").Ī logical OR implies the following truth table:Ġ 1 1 (a OR b or Both, a and b, must be true to get a true result)Ī logical AND implies the following truth table:ġ 1 1 (Both a AND b, must be true to get a true result) To convert a raw encoded character to ascii we have to make boolean operationsīetween this two operands (0xc3 and 0xb1), boolean algebra were defined by Georgeīoole, we need to use them here. They are binary numbers, (HHHH LLLL, where HHHH=High and LLLL=Low).Ġxc3 = 1100 0011 (binary 8 bit word), 0xb1 = 1011 0001 (binary 8 bit word), This is nothing more and nothing less than 0xc3 and 0xb1, ( 0xc0 | ( $hex_table įor example, you have the character "ñ" encoded like this "%C3%B1". They are not decoded with rawurlencode(), so I've made this: I've had a little issue with latin characters like ñ","Ñ","á","é","í", etc. Hi everybody =) My name is Javier and I'm from Argentina.
