Remarks

The safe list affects all HTML XML, CSS, and URL encoding methods.

With some exceptions, Unicode code charts do not directly correspond to written languages. To add support for a specific language or set of languages often requires marking multiple code charts as safe.

To add support for the Japanese language while continuing to allow English, use the following syntax:

MarkAsSafe(  
            LowerCodeCharts.Default,  
            LowerMidCodeCharts.HangulJamo,  
            MidCodeCharts.None,  
            UpperMidCodeCharts.CjkRadicalsSupplement |   
            UpperMidCodeCharts.CjkSymbolsAndPunctuation |   
            UpperMidCodeCharts.Hiragana |   
            UpperMidCodeCharts.Katakana |   
            UpperMidCodeCharts.KatakanaPhoneticExtensions |   
            UpperMidCodeCharts.LatinExtendedD |  
            UpperMidCodeCharts.CjkUnifiedIdeographs,
