RadEditor is powerful enough to be used in any language you like: English, Bulgarian, Serbian, Russian, Hindi, Vietnamese, Chinese, Japanese, Korean, etc, because its content area is a standard editable IFRAME element which uses the Rich Text Editing engine of the browser. This engine offers support for Japanese characters.
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.
I tried to reproduce the problem but without success. You can see my test at: http://screencast.com/t/NTk2YjhjYWI
