Convert PHP function to Autoit ?

Recommended Posts

anOldLongUser

Hello sirs,

recently i have problem converting some facebook API result to UTF 8, i found this PHP function which works great, but it would be so great if autoit can do same kind of job, i would be grateful if some one can help. thank in advance

<?php
 $a='Bu\u00f4\u0300n c\u01b0\u01a1\u0300i ch\u00ea\u0301t \u0111\u01b0\u01a1\u0323c :v';
 
 
 echo $str = preg_replace_callback('/\\\\u([0-9a-fA-F]{4})/', function ($match) {
    return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UCS-2BE');
}, $a);
 
 
?>

Looks like preg_replace_callback is essential two calls in autoit,

one is a StringReplace() (using StringRegEx) and then this calls a function that has the replaced string as an argument

The Second mb_convert_encoding is converting that replaced string to a different character encoding. I dont know much about this but I found a topic with:

 

Func Asc2Unicode($input)
    If StringLen($input) <> 1 Then Return SetError(-1, -1, -1)
    Local $FullUniStr = DllStructCreate('byte[3]')
    Local $Buffer = DllStructCreate('byte[2]', DllStructGetPtr($FullUniStr) + 2)
    Local $Return = DllCall('Kernel32.dll', 'int', 'MultiByteToWideChar', _
            'int', 0, _
            'int', 0, _
            'str', $input, _
            'int', StringLen($input), _
            'ptr', DllStructGetPtr($Buffer, 1), _
            'int', 2)
    DllStructSetData($FullUniStr, 1, 0xFF, 1)
    DllStructSetData($FullUniStr, 1, 0xFE, 2)
    Local $temp = DllStructGetData($Buffer, 1)
    Return '\u' & StringMid($temp, 5, 2) & StringMid($temp, 3, 2)
EndFunc   ;==>Asc2Unicode

The encoding you want:

FE FF = UCS-2 (16bit) big endian

so I THINK! that the above should be converted to 

Func Asc2Unicode($input)
    If StringLen($input) <> 1 Then Return SetError(-1, -1, -1)
    Local $FullUniStr = DllStructCreate('byte[3]')
    Local $Buffer = DllStructCreate('byte[2]', DllStructGetPtr($FullUniStr) + 2)
    Local $Return = DllCall('Kernel32.dll', 'int', 'MultiByteToWideChar', _
            'int', 0, _
            'int', 0, _
            'str', $input, _
            'int', StringLen($input), _
            'ptr', DllStructGetPtr($Buffer, 1), _
            'int', 2)
    DllStructSetData($FullUniStr, 1, 0xFE, 1)
    DllStructSetData($FullUniStr, 1, 0xFF, 2)
    Local $temp = DllStructGetData($Buffer, 1)
    Return '\u' & StringMid($temp, 5, 2) & StringMid($temp, 3, 2)
EndFunc   ;==>Asc2Unicode

Converting \u**** sequences into AutoIt (Unicode) is done like that:

Local $string = 'Bu\u00f4\u0300n c\u01b0\u01a1\u0300i ch\u00ea\u0301t \u0111\u01b0\u01a1\u0323c :v'
$string = Execute('"' & StringRegExpReplace($string, '\\u([[:xdigit:]]{4})', '" & ChrW(0x$1) & "') & '"')
MsgBox(0, "", $string)

Are you sure you then need to convert the string to UTF8? AutoIt string are Unicode UTF16-LE, not UTF8. But if you actually need to do so, you can use this:

$UTF8string = BinaryToString(StringToBinary($string, 4), 1)

Note: the functions posted as examples a few posts above are incorrect.

Out of curiosity, What was wrong with the code above? I was able to write an example that converted a string to \u codes. The function posted above converts 1 character at a time.

 

was the encoding backwards? \u codes -> ascii instead of ascii -> \ucodes

I was rather refering to the functions in the post linked to.

Then the OP wanted \uXXXX -> native AutoIt string (UCS-2LE).
