The WYSIWYG Fonts dropdown of RadEditor display a predefined set of fonts which by default are: Arial, Comic Sans MS, Courier New, Tahoma, Times New Roman and Verdana. All fonts are set using the FontNames Collection.You can predefine the FontNames Collection by modifying the ToolsFile.xml / ListToolsFile.xml files, located in the following folder:
/Program Files/Common Files/Microsoft Shared/web server extensions/wpresources/RadEditorSharePoint/6.x.x.0__1f131a624888eeed/Resources/
<root> <tools name="MainToolbar" enabled="true"> <tool name="FontName" /> </tools> <fontNames> <item name="Arial" /> <item name="Arial Narrow" /> <item name="Arial Black" /> </fontNames> </root>
The fonts must be available on the client machine.
RadEditor is powerful enough to be used in any language you like: English, Bulgarian, Russian, Hindi, Vietnamese, Chinese, Japanese, Korean, etc.
You'll need to set the proper encoding in the aspx files with the editor. You can use the following encoding:
<?xml version="1.0" encoding="utf-8" ?>, which will make the editor compatible with Western Europe languages, Cyrillic, Greek, Asian, Arab, Chinese, Japanese, etc characters.
If the characters are displayed properly by the browser on the same page where the editor is, they should be displayed properly in the editor as well.
