Determining the page encoding of server output
Before ColdFusion can return a response to the client, it must determine the encoding to use for the data in the
response. By default, ColdFusion returns character data using the Unicode UTF-8 format.
ColdFusion pages (.cfm pages) default to using the Unicode UTF-8 format for the response, even if you include the
HTML
tag in the page. Therefore, the following example doesnot modify the character set of the response:
meta
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
