Unwanted ligatures

Please, do not allow ligatures, such as "�" for "fi", in log output. This is a common problem these days with many monospaced rendering and has to be disabled explicitly. See attachment for example.

I don't see this behavior on my, Window 7, system.
From the code I see:
m_outputLog = new QTextEdit;
m_outputLog->setReadOnly(true);
m_outputLog->setFontFamily(QString::fromLatin1("courier"));

So my guess is that the courier font cannot be found in your case.

Which platform are you using?

Ubuntu latest and I have that font.

This is a common default setting on (HTML) text rendering that is highly undesirable when displaying text in monospaced font. That it shows fi ligatures indicates that there is very good font support, as these are special font features.

In CSS, this is fixed by

style='font-family: courier; -o-font-feature-settings: "liga" off; -o-font-variant-ligatures: none; -moz-font-feature-settings: "liga" off; -moz-font-variant-ligatures: none; -webkit-font-feature-settings: "liga" off; -webkit-font-variant-ligatures: none; font-feature-settings: "liga" off; font-variant-ligatures: none; '

@pander: Maybe it would be a fix to use

m_outputLog = new QPlainTextEdit

instead of

m_outputLog = new QTextEdit.

in addon/doxywizard/doxywizard.cpp

Can you try if that helps?

For this project, I am only a user. Please ask somebody else to reproduce and confirm the proposed fix. Thanks.

On RHEL6 this problem didn't show but the text was displayed in italics.
Changing to QPlainTextEdit didn't solve the problem.
With QTextBrowser it was possible to overcome the problem.

I've just pushed a proposed patch to github (pull request 451)
