Question

I have googled on this topic and I have looked at every answer  but I still don t get it   Basically I need to convert UTF-8 string to ISO-8859-1 and I do it using following code   Encoding iso   Encoding GetEncoding  ISO-8859-1    Encoding utf8   Encoding UTF8  string msg   iso GetString utf8 GetBytes Message      My source string is  Message                        But unfortunately my result string becomes  msg                                   What I m doing wrong here

Seems bit strange code  To get string from Utf8 byte stream all you need to do is   string str   Encoding UTF8 GetString utf8ByteArray     If you need to save iso-8859-1 byte stream to somewhere then just use  additional line of code for previous   byte   iso88591data   Encoding GetEncoding  ISO-8859-1   GetBytes str

Use Encoding Convert to adjust the byte array before attempting to decode it into your destination encoding   Encoding iso   Encoding GetEncoding  ISO-8859-1    Encoding utf8   Encoding UTF8  byte   utfBytes   utf8 GetBytes Message   byte   isoBytes   Encoding Convert utf8  iso  utfBytes   string msg   iso GetString isoBytes

I think your problem is that you assume that the bytes that represent the utf8 string will result in the same string when interpreted as something else  iso-8859-1   And that is simply just not the case  I recommend that you read this excellent article by Joel spolsky

You need to fix the source of the string in the first place   A string in  NET is actually just an array of 16-bit unicode code-points  characters  so a string isn t in any particular encoding   It s when you take that string and convert it to a set of bytes that encoding comes into play   In any case  the way you did it  encoded a string to a byte array with one character set  and then decoding it with another  will not work  as you see   Can you tell us more about where that original string comes from  and why you think it has been encoded wrong
