Looking if any character whose ascii code is greater than 127

VRonin

can you post the content of m_commandFile? is it a text or binary file? I think you are doing serialisation wrong. return QString(m_commandFileContent); smells a lot

How can I post the content of the file ?

VRonin

We just want to understand what's in that file. is it a .txt file containing text, is it a binary file (image, document, etc)?

Here is the start of the file:

@Comt = Based on
L : Litolff’s / 1880
B : Breitkopf / 1890
P : Peters / 1892

The trouble is the character ' after Litolff

It's a text file with CR and LF (0d 0a) at the end of each line

If you have a text file, then read it as a text file! Why are all those shenanigans even needed?

QFile file("C:/path/to/file");
if (!file.open(QFile::ReadOnly | QFile::Text)) //< Open as text file so you get CL/LF conversions properly
    ; //< Can't open file, handle accordingly

QTextStream in(&file);
while (!in.atEnd())  {
    QString line = in.readLine();
    // ... do something with he line ...
}

At the very beginning, I read it as a text file. The problem was that I got LF instead CR LF and I need CR LF to rewrite the file content into another file

That's because there are line ending conversions done depending on the OS. It's not a problem!
You read it as a text file, and you get "\n" where the newline is. When you write it as a text file "\r\n" will be written wherever there's "\n". That's the difference between text and binary files.

The trouble is that the file I write to is binary because I append text files and binary files

mulfycrowh

It runs if I use this:

bool Tools::searchIncoherentAscii(const QString &content)
{
	int j;
	for (int i = 0; i < content.length(); i++)
	{
		j = content.at(i).unicode();
		if ( j > 127) return true;
	}

use QString::replace("\n","\r\n");

@VRonin Many thanks for your help. I sent you a private message onto your mailbox about another subject. Could you please have a look ?
