[Octave-bug-tracker] [bug #42136] Unicode box drawing chars in GUI don't line up very well

[Colin Macdonald]

Follow-up Comment #20, bug #42136 (project octave):

Aha!  That explains why when I increase the font size, the lines of box
drawing chars alawys stay 1-pixel thin.  This isn't a nice behaviour for
high-dpi screens...  Upstream active?

I did this:

diff -r b4a9888bb3c9 libgui/qterminal/libqterminal/unix/TerminalView.cpp

-static inline bool isLineChar(quint16 c) { return ((c & 0xFF80) == 0x2500);}
+static inline bool isLineChar(quint16 c) { return (false);}
 static inline bool isLineCharString(const QString& string)
 {
   return (string.length() > 0) && (isLineChar(string.at(0).unicode()));

And now box drawing looks fine on my system...
