IniWrite accented characters to existing UTF8-BOM .ini file

[Steviep]

Hi all, i'm updating an installer script which must write French text with accented characters to existing .INI preference files encoded with UTF8-BOM.

IniWrite ( "UTF8-BOM.ini", "section", "key", "é")

When I attempt to do so, the é character appears scrambled.

I've been reading through the Help documents and see we can use FileOpen for new files, but in this case I'm updating existing files.

I have also been reading lots of other community posts related to this and understand there are limitations with .ini files & UTF8-BOM.

I've been experimenting without success, any suggestions? Thanks.

$FO_APPEND + $FO_UTF8?

 I tried mode 129 ($FO_APPEND + $FO_UTF8) with FileOpen but still no luck:

#include <File.au3>

$file = "UTF8-BOM.ini"
$Open = FileOpen ( $file, 129)
IniWrite ( $file, "section", "key", "é")
FileClose ($Open)

See result in screenshot attached.

@Steviep
Pass to the IniWrite functions the handle obtained by FileOpen instead of the filename, and let us know

You need to use FileOpen with the UTF 16 LE mode to read/write Unicode to an INI file.

Quote

$FO_UNICODE or $FO_UTF16_LE (32) = Use Unicode UTF16 Little Endian reading and writing mode.

Try that instead of the $FO_UTF8 mode.

I tried the following but instead, it created a new file name called "1"

#include <File.au3>

$file = "UTF8-BOM.ini"
$Open = FileOpen ( $file, 129)
IniWrite ( $Open, "section", "key", "é")
FileClose ($Open)

@BrewManNH

I tried with 32 instead of 129, but seem to have the same results:

$file = "UTF8-BOM.ini"
$Open = FileOpen ( $file, 32)
IniWrite ( $file, "section", "key", "é")
FileClose ($Open)

NotePad++ is showing that the file is UTF8+BOM which is good but I just can't seem to write these characters to it.

I ran your script, and it worked fine for me.

I ran this:

$file = "UTF8-BOM.ini"
$Open = FileOpen ( $file, 33)
IniWrite ( $file, "section", "key", "é")
FileClose ($Open)
ShellExecute($file)

I got this in the INI

Quote

[section]
key=é

You're right that it does work if the UTF8-BOM.ini file does not exist, but in my case i'm updating an existing .ini file which was previously encoded with UTF8-BOM.

Do you think there's a way to write these characters directly to an existing UTF8-BOM .ini?

[BrewManNH]

No

@Steviep

Another wat would be to read the content of the existing UTF-8 file and write it back with the desired format

@FrancescoDiMuro

In the end, this is exactly what I decided to do. Thanks for your assistance!

Happy to have helped

Hi,

I have the same Problem, but on my side it doesn't work like here posted.

My ini File is in UTF8-BOM (according to notepad++). 

If I want change a value it will always be append on these File.

Have anybody has an idea what I make wrong?

 

Thanks

@MatzeP, You really need to provide your source and a copy of that ini file if you want anybody to assist unless they have that famous crystal ball.

Func _Ini_Initialization($sFile, $sSectioName)
    If FileExists($sFile) Then Return
    Local $h_file = FileOpen($sFile, 2 + 32) ; 32 = Use Unicode UTF16 Little Endian reading and writing mode.
    FileWrite($h_file, $sSectioName & @CRLF) ; you need to write something
    FileClose($h_file)
EndFunc   ;==>_Ini_Initialization
_Ini_Initialization(@ScriptDir & "MPV-Enhancer.ini", "[Settings]")

I always create ini-files this way, ini-file must not exist initially.

[MatzeP]

Hi,

Yes your are right:

Func Main()
    $NexusMeteringPathWorkDir=StringRegExp($NexusMeteringPath,"(^\w:\\.*\\).*\.exe",2)

        For $i=1 To $WindowQue[0]

             iniWrite($iniNexusConfigFile,"GLOBAL","AktPage",$i)
            Sleep(1000)
            Run($NexusMeteringPath, $NexusMeteringPathWorkDir[1])
            Sleep(2000)
        Next
EndFunc

In $WindowsQue is a List of numbers which I must change step by step. So that the Program start with the right parameters.

The ini-File is written by another Program and is written after every start of the Program.

I will only change one entry.

 

@Kafu: I have test it with FileOpen(***,32,33,128,129,256,257) and always he set the entry at the End. 130 and 258 overwrite my file and only my one entry is inside.
