Unicode characters not showing in System.Windows.F

问题:

These characters show fine when I cut-and-paste them here from the VisualStudio debugger, but both in the debugger, and in the TextBox where I am trying to display this text, it just shows squares.

I thought that the TextBox supported Unicode text. Any idea how I can get this text to display in my application?

回答1:

You need to install and use a font which supports those characters. Not all fonts support all characters. the [] box character is the fonts representation of 'unsupported'

The textbox might be using MS Sans Serif by default, so change it to Arial or something else.

回答2:

I changed from using a TextBox to using a RichTextBox, and now the characters display in the RichTextBox.

回答3:

I was facing similar problem.

It was problem with reading file properly and not with TextBox control.

StreamReader reader = new StreamReader(inputFilePath, Encoding.Default, true)

Copied from THIS.

Works for me and that too without switching to RichTextBox.
