Problem

I'm trying to convert from ASCII to HEX in PHP but get a different result to some of the online tools that are available. I know the result I'm looking for so the online tool's result appear to be correct and my code incorrect but I can't work out why. ``` String: 2Ffbj?DoyXOU Correct output: 32 46 66 62 6a 3f 44 6f 79 58 4f 55 (from linked site above) My output: 32 46 66 62 6a 3f 44 6f 79 58 4f 75 ``` My script: ``` echo bin2hex(utf8_decode("2Ffbj?DoyXOU")); ``` Where is the fault?
