Hello,

here are http://www.utf8-chartable.de/unicode-utf8-table.pl?start=960 0&number=128
some utf8 characters and relative code that I would like to show in a LineEdit.

Unfortunately I am able to show few of them while others appear as white box. I have read that this depends by the font installed on my computer. On this topic I am very confused. I have two questions:

1) is there some specific font Upp compatible that let me show most of the graphical characters (I need circle/square full/half white/black colored and some arrows);

2) What will happen to other users of my app if he does not have the same font?

If this is not possible within Upp I'll try to work with HTML document.

Thanks,
Luigi

Hi Luigi,

If you are using windows then "Arial Unicode MS" will be available. It has all characters. There is Linux equivalent available.

Enclosed sample code.

I have not set special font. It is system default StdFont().

If with stdfont you are not getting desired result then you can set font like this

        int FontIndx = Font::FindFaceNameIndex("Arial Unicode MS");
	Font MyFont = Font(FontIndx,20);
	LineEdit.SetFont(MyFont);

Hi Deepak,

thank you for the answer.
Your test case works on my systems (windows XP and linux lubuntu).
In general everything works when I create text files with Upp and then display it by linedit. But it fails when the text file are made by other programs (no Upp) and I import it in linedit.
Who creates the text file (via a Java program) assure me it is utf-8 encoded Rolling Eyes .

Best regards,
Luigi

Hi Luigi,

One suggestion. Check the files created by other application using notepad++. If it shows all characters as expected then mostly UPP will also display it properly.


Warm Regards

Deepak
