ANSI vs SHIFT JIS vs UTF-8 in C #

Question

I’ve been trying to understand the difference for quite some time. The problem with the ANSI encoded file has Japanese characters, such as: ­‚È‚­‚Æ‚à1‚‚ÌINCREMENTs‚ª•K—v‚Å‚·.It is equivalent to shift-jis 少なくとも1つのINCREMENT行が必要です., which is expected to be in Japanese.

I need to display these characters after reading from a file (in ANSI) on a web page. There are other files in UTF-8 that display characters without seeing this. I find it hard to understand what the difference is and how to change the encoding to do the right thing here. I use C # to read this file and display it, I also need to write the line back to the file if it has been modified on the Internet. Any encoding and decoding schemes here?

As for code pages, “ANSI” (and Encoding.Defaultin .NET) basically just means “non-Unicode code page used by this system” - exactly which code page that exists depends on how the system is the Western European system is most likely Windows-1252.

For the system where this text comes from, then “ANSI” will mean Shift-JIS, so if your system does not have the same code page, you need to tell your code to read the text as Shift-JIS.
