System.Text.RegularExpressions.RegexParseException: Invalid pattern

[iansmirlis]

Hello

Readability.CleanTitle() should properly escape string variable siteName with Regex.Escape() before it's applied as Regex Pattern, otherwise could lead to strange behavior as the following:

System.Text.RegularExpressions.RegexParseException: Invalid pattern '(.*) [|-\/>»] «Τζιαι τούτοι σάλια, αρκοφωνές τζιαι ποταμούς μελάνιν»*.' at offset 73. Nested quantifier '*'. at System.Text.RegularExpressions.RegexParser.ScanRegex() at System.Text.RegularExpressions.RegexParser.Parse(String pattern, RegexOptions options, CultureInfo culture) at System.Text.RegularExpressions.Regex..ctor(String pattern, RegexOptions options, TimeSpan matchTimeout, CultureInfo culture) at System.Text.RegularExpressions.RegexCache.GetOrAdd(String pattern, RegexOptions options, TimeSpan matchTimeout) at System.Text.RegularExpressions.Regex.Replace(String input, String pattern, String replacement, RegexOptions options) at SmartReader.Readability.CleanTitle(String title, String siteName) at SmartReader.Readability.GetArticleMetadata(IHtmlDocument doc, Uri uri, String language, Dictionary`2 jsonLD) at SmartReader.Reader.Parse() at SmartReader.Reader.GetArticle()
