The same for me, I receive messages in "windows-1257" encoding (Lithuania).

I get "?" instead of every custom symbol of my language.

For example, I get: "Labas rytas, ?iandien Rytin?se finans? rin? naujienose:...", but i should get: "Labas rytas, šiandien Rytinėse finansų rinkų naujienose:...".

Upon investigation, I spotted one bug in InternetTextMessage.ParseContentEncoding, when my mentioned "windows-1257" encoding was not parsed at all, because format in message header had spaces:

Content-Type: text/plain; charset = "windows-1257"


// InternetTextMessage.cs

// ParseContentEncoding method

///charset=???; also may contain space: charset = ???;
m = Regex.Match(inLine, ".*charset ?= ?[\"]*(?<Value>[^\"]*)[;\n\r]", RegexOptions.IgnoreCase);

///charset=??? also may contain space: charset = ???
m = Regex.Match(inLine, ".*charset ?= ?[\"]*(?<Value>[^\"]*).*", RegexOptions.IgnoreCase);

// Note that I added " ?" to regex expressions, so now both formats "charset=windows-1257" and "charset = windows-1257" are recognized.

Although my above post fixed error when content-encoding was not parsed correctly, I still get ? instead of special symbols. :(

If it will be helpful, I can include raw text of email, as seen from my email client:

Perhaps recent update(2010/4/30) may modify this issue.
Pop3Client class always use encoding ascii in old version.
I add ResponseEncoding property to Pop3Client class.
Set this property UTF-8 and propably you may get correct  char.
