Hi Rangel, for PHP 6 the basic string type ist "unicode string" and most functions will accept these as primary type. But there are a few exceptions where unicode, for different reason, makes no sense. There you have to pass a binary string - an example is the mentioned urlencode(): It has to work on bytes to be reliable but it has no clue on the proper encoding so you need to tell that function "Yes the, I know about the meaning, just take this byte sequence".
A good thing would be to check the archives where most reasons were posted before. johannes On Tue, 2007-05-22 at 15:16 -0300, Rangel Reale wrote: > I'm also having problems with this b"string" incompatibility with older > versions, I know I shouldn't need to have binary strings, but the problem > is, the PHP funcions does not accept an Unicode string (urlencode), so it > gives me a warning. > > In the future will 100% of the functions accept an unicode string?
