Unicode characters not showing in System.Windows.Forms.TextBox

Question

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.

說明\r\n海流受季風影響，3-9 月份其流向主要向北，流速爲2 節，有時達3 節；10 月至次年4 月份其流向南至東南方向，流速爲2 節。\r\n注意\r\n附近有火山爆發的危險，航行時嚴加註意\r\n

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

Answer 1

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

Answer 2

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.

Answer 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 .
