Symptoms

If an HTML document contains a <META> tag that includes the parameter 'charset=unicode', and the server does not set character encoding in 'ContentType' header, then APM enforces UTF-16 encoding for this document which may be wrong.

Impact

A UTF-8 HTML page may be shown incorrectly if it has a <META> tag that includes the 'charset=unicode' parameter.

Conditions

This occurs on an HTML page in UTF-8 encoding with the following tag: <META content="text/html; charset=unicode" http-equiv=Content-Type> Back-end server does not set default document encoding.

Workaround

There is no workaround.

Fix Information

APM displays UTF-8 HTML pages correctly.
