When I try to get some text from file and display it in textbox it is okay until I want to write Czech characters (e. g. 蚞). They show up like: Moj� nejv�t�� z�libou je �e�en� koresponden�n�ch semin���
Should I set encoding to loaded text just before I assign it to textBox1.text or it is possible to change encoding of textBox1.Text itself?
I use following code:
textBox1.Text = File.ReadAllText(file);
Try to force the encoding (the machine default should be OK, if you don't know the correct one):
textBox1.Text = File.ReadAllText(file,Encoding.Default);
Anyway, being Czech I guess your current default encoding is "Western European (Windows)" (you can get it also doing Encoding.GetEncoding(1252))
That is also the one on my pc (I have an Italian version of Win7).
This method attempts to automatically detect the encoding of a file based on the presence of byte order marks. Encoding formats UTF-8 and UTF-32 (both big-endian and little-endian) can be detected.
Use the ReadAllText(String, Encoding) method overload when reading files that might contain imported text, because unrecognized characters may not be read correctly.
Try using the other overload to explicitly specify the Encoding since automatic detection is not working in your case, something like
textBox1.Text = File.ReadAllText(file, Encoding.UTF8);
