In order to show the characters other than the English characters on your website, you may need to use the below coding on your CFM script.
Here is a sample of coding for Chinese characters.
<cfprocessingdirective pageEncoding="gb2312">
<cfcontent type="text/html; charset=x-EUC-CN">
<cfset setEncoding("URL", "gb2312")>
<cfset setEncoding("Form", "gb2312")>
If you would like to know the charsets that are use in ColdFusion, you may refer to http://www.sustainablegis.com/projects/i18n/charsetTB.cfm
