ASCII Character Codes Chart 2Hello, I want to use the above characters codes chart but I dont know how to
set the typeface (documentation: The characters that appear in Windows above 127 depend on the selected typeface). For example, when I print the chr(205), I am not getting the one shown in the Chart 2 list...

You are using the chr function. It uses the current ANSI codepage (here 1252 "Westeuropean (Windows)"). On that page, character #205 looks different to that on the chart you are referring to. What your code does is: Create as string containing characters 128 to 255 from the current ANSI codepage - not from codepage 437 like on the chart. Then you convert back to exactly the same array because you are again using System.Text.Encoding.Default. After that, you use code page 850 to convert that array to a string again. This doesn't make sense because a) superfluous string <-> byte array converions b) different assumptions of the code page used for the character codes in the array (ansi vs. cp 850). In the end, the code does the same as the one I gave already before. The only difference is that I showed only one character instead of 128-255. You can make your code much less complicated: Dim b(127) As Byte Dim en As Encoding = Encoding.GetEncoding(850) Dim s As String For i As Integer = 128 To 255 b(i - 128) = CByte(i) Next s = en.GetString(b) Armin > That's a different bet. :-) I showed you how to convert a character code to The idea was to map bytes 128..255 to their cp850 values just to see the > a string applying a certain code page.

I should have looked first at your answer. (Armins answer is of course as well correct) As you probably know did I hate forever that 850 one "International Latin", from which every hardware seller was setting the computers in Holland, while the 437 was more proper for Holland, because it has a florin character. (And than 50% in Holland became 437 and the other half 850). Now we have luckily almost all in Germanic/Roman derived languages the 1252. Nice link by the way, I have replaced that one you probably have seen from Athene by this one, although I keep this one http://www.microsoft.com/globaldev/reference/oslocversion.mspx :-) Cor
