C# and HtmlAgilityPack encoding problem

半腔热情 提交于 2019-11-28 09:40:50
WebClient GodLikeClient = new WebClient(); HtmlAgilityPack.HtmlDocument GodLikeHTML = new HtmlAgilityPack.HtmlDocument(); GodLikeHTML.Load(GodLikeClient.OpenRead("www.alfa.lt"); So this code returns: "Skaitytojo klausimas psichologui: kas lemia homoseksualumÄ…? - Naujienų portalas Alfa.lt" instead of "Skaitytojo klausimas psichologui: kas lemia homoseksualumą? - Naujienų portalas Alfa.lt". This webpage is encoded in 1257 (baltic), but textBox1.Text = GodLikeHTML.DocumentNode.OuterHtml; returns the distorted text - baltic diacritics are transformed into some weird several characters long
