All those free email services are web based email services. As with all web pages, whether you can view/input Chinese/Japanese/Korean (CJK) text correctly depends on the page encoding. If your windows is non-CJK version, the page encoding is not CJK by default. To view/input CJK correctly on those webmail, please right click your mouse on a blank spot on the page, then select 'encoding' from the pop-up menu, and then select one of the following encodings:

• For Simplified Chinese, select GB-2312, GB-18030 or Unicode UTF8;
• For Traditional Chinese, select Big5 or Unicode UTF8;
• For Japanese, select Japanese(Auto-Select) orUnicode UTF8;
• For Korean, select Korean KSC or Unicode UTF8

You need to set correct encoding if 1). the page is not displayed as you expect, and 2). before you start inputing CJK text.
