Encode up to one byte extended ascii values

Question

In C #, there is a way to encode extended ascii values ​​(128-255) into their single byte values, as shown here: http://asciitable.com/

I tried using Encoding.UTF8.GetBytes (), but it returns multibyte values ​​for extended codes. I need nothing but 255, but it would be nice to at least support them. I am trying to send text data to an Arduino controlled and LED matrix and want to process letters with an accent without dealing with multibyte characters.

EDIT: To clarify, the LED matrix does not have a special code page. That is basically all I say. There is no built-in text support or arduino. This is just a dumb display with a resolution of 128x8 pixels, and the controller manually draws a pixel of text by pixels. Therefore, I actually provide it with a font (like an array of bytes in the header file) and can make any character code match any of the results that I want ... therefore, which code page to use is not a problem, except which will give me full 8-bit characters.

Answer 1

Just pass the code page number to the Encoding constructor. If you linked the correct "extended ASCII" table, it will be 437 .

But the IBM437 encoding is unusual outside of DOS programs and Windows console applications. Otherwise, the standard encoding for Western European languages ​​is ISO-8859-1 (Windows code 28591) or windows-1252 .

Answer 2

You need to know the code page that the LED matrix uses. It should be standard, such as 1252, the Windows codepage for Western Europe and the Americas.

  var bytes = Encoding.GetEncoding(1252).GetBytes("Åãrdvárk"); 

Answer 3

Default coding should handle this. Or use ANSI encoding / encoding.
