Unicode String in TreeView

[miztaken]

Hi,
I have a string with some unicode characters and when i tried to
displayed it in TreeView its not displaying.

I am doing like this:
TreeNode tn = new TreeNode("unico destring");
treeView.Nodes. Add(tn);

i can see the unicode characters in DEBUG mode in Visualizers (XLM,
HTML and TXT) but i cant see it on TreeView, it gets displayed as
squares.


What am i doing wrong here?

miztaken,

Do you see them on your own developing computer wrong or in a seperated
computer?

FYI: in this context, the phrase "a string with some unicode characters"
is redundant, if not nonsensical. In C#, all strings are Unicode
strings. All characters in a string are Unicode characters. It happens
that some Unicode characters share the same numerical value as some
non-Unicode characters, but that doesn't keep them from being Unicode
characters.

I am doing like this:
TreeNode tn = new TreeNode("unico destring");
treeView.Nodes. Add(tn);

You're using a font for the TreeView that doesn't include glyphs for the
characters you're trying to display. You should use a different font, one
that does have glyphs for those characters.

Hi Pete,
Thanks for the reply.
I am using default Arial font for TreeView.
I have tried using Tahoma and Times New Roman and still the same case.
Which font do you suggest ?

And wont we have some condition where the used font might fail for the
text to be displayed? How can we handle such case?

thank you

Yes, it's always possible that the font you want to use won't show the
characters you want to use. I'm not aware of any font that has _every_
possible Unicode character, and even if such a font exists, it's not
necessarily one that has a suitable look for your needs.

That said, fonts generally support specific ranges of characters, so
assuming the characters you're using have something in common with each
other with respect to their placement within the Unicode space, a font
that supports any of the characters you're specifically trying to use will
probably support all of the characters you're trying to use.

The only way to know for sure though is to test it, or at least check all
of the characters supported by the font.

I see from your follow-up that you found a font that works, so hopefully
that means that font will support all of the characters you're trying to
use. Without knowing exactly the characters, I can't say for sure that it
will. But you've got good odds that it will. :)

Yea, you are true.
Thank you very much for sharing your thoughts.

Windows in general does a good job to find a font that works.
(things like font fallback, font linking, font substitution)

Are you on XP? And if yes, do you have the proper support installed?

Try "Control Panel" - "Regional and Language Options" -- second
tab, "Languages" , make sure to check the two checkboxes under
the "Supplement al language support" group
