I\'m trying to fetch and parse an online excel document which is written in hebrew but unfortunately in a non-hebrew encoding.

As an example I\'m trying to convert t

Answer 1

const string Str = "âìéåï_1";

Encoding latinEncoding = Encoding.GetEncoding("Windows-1252");
Encoding hebrewEncoding = Encoding.GetEncoding("Windows-1255");

byte[] latinBytes = latinEncoding.GetBytes(Str);

string hebrewString = hebrewEncoding.GetString(latinBytes);

hebrewString:

גליון_1

In your supplied example "Window-1252" is not actualy ASCII, it is extended ASCII, and for some reason Encoding.Convert with these two encodings cannot convert extended range ASCII, so all +127 characters are converted as 63 (i.e. ?). When "converting" from one extended ASCII character byte[] to another, I would expect the bytes to be the same, it is only when you convert them to a .Net unicode string I would expect them to be different. Not sure why Convert is converting +127 chars to '?'.
