Extended Ascii Codes in QTextEdit

[mulfycrowh]

Thank you. That's exactly what I meant !

[mulfycrowh]

Is it the only way to achieve this ?

[hskoglund]

Hmm you mean you don't like QChar? If you only want to use QString stuff, you could rewrite it (output looks the same) to:

    QString s;
    for (ushort u = 0; (u < 2048); ++u)
        s += QString::fromUtf16(&u,1);

    ui->textEdit->setText(s);

[mulfycrowh]

I tried this:

QString s;
s = "test ";
s += QChar(225);
ui.Test->setText(s);

It does display "test a", a with accent instead of "test ß".

Because the 225th char in the utf-16 table[1] is an á. QChar is a single character (2 bytes) in utf-16.

@kshegunov Thank you. So how can I manage it to get the character ß ?

[kshegunov]

You go to the wiki page and at the bottom you find what's the codepoint of said character in unicode. Then you google that and you get this nifty page. Finally you get the code for the character and insert in as an argument of QChar:

s += QChar(223);

[mulfycrowh]

I tried this:

		QString s;
		s = "test ";
		ushort u = 223;
		s += QString::fromUtf16(&u, 1);
		u = 147;
		s += QString::fromUtf16(&u, 1);
		ui.Test->setText(s);

ß is displayed but not the second one (").
Does it show that extended characters' display in QTextEdit is not possible ?

Firstly, there's no "extended characters", there are different encodings for representing text and Qt uses utf-16. Secondly, showing text in QTextEdit is possible and if the font you're using has a glyph for the character you're trying to display, then the character will be displayed. And finally, have you checked what is corresponding to the number 147 in the first utf-16 table I've posted as a link? I see no corresponding character for that code, so what are you expecting to see exactly? Where do you get 147?

[mulfycrowh]

I found this table:

and you get the characters with the matching decimal code

Explanation: I have a file with hex bytes equal to 93, 94, 96 ... and I would like to display the matching characters into a QTextEdit.

[mulfycrowh]

I found the solution in adding fromLatin1()

[mulfycrowh]

With fromLatin1(), it's better: I have no more losange with ? but, for example hex codes 93 and 94 are not displayed.

[mulfycrowh]

From Wikipedia, I copy and paste some text.
In this text I have the character (Hex 92) (') and the character (Hex E9) (é).
The second one is displayed. The first one is replaced by a chinese character.
Why ?

[mulfycrowh]

I think having found the perfect solution :)

I copied and pasted many articles from Wikipedia in French, English and German and it runs.
The solution is to use:

FromLocal8Bit()

[kshegunov]

As long as it works for you. I wouldn't depend on the local 8bit encoding myself, but that's just me.

[mulfycrowh]

@kshegunov That's the only way to make it perfectly running. Do you have other idea in mind ?
