when I use salfilewrite function to write a string in file,

string of ascii is fine.But string of unicode was wrote



Call SalFileOpen(hFile,'C:\\filetest.txt',OF_Create)

Call SalFileWrite(hFile,'12345')

Call SalFileClose(hFile)

Hi Kevin

Everything is UTF-16 in TD 5.1. When writing a file as it used to be with previous version the result is an ANSI file. So we convert from UNICODE to ANSI using your local page...If you have mixed UNICODE charset some not being part of you local page the conversion beeing done will fail with "?" for those char. To save data as UNICODE use OF_UTF16 flag in SalFileOpen() this will create a unicode file and all charset can be saved then.

As you can see, currently it is not possible to directly open and read properly an ANSI file of a different code page say ARABIC CP1256, nor it is possible to convert UNICODE ARABIC charset to ANSI CP directly. You can do that INDIRECTLY by opening the file as OF_BINARY and make the conversion of the buffer using SalStrToMultiByte()/SalStrToWideChar() with the right code page (the constant we define there are not limited to what we give in the coding assistant)...So you can use 1256 as a code page to this function, this works as long as the code page is installed on your machine. See

I believe we will improve SalFileOpen to allow this to be done automatically by passing the Code Page you like to use.
