Zoho Writer Remote API problem (html-code in the doc file)

We are trying to use Zoho Writer Remote API and have problems.

I'm trying to open .TXT file, and if this file contains html-symbols (e.g. < or ") Zoho Writer interprets these symbols as HTML.
So, content of opened file is wrong � Zoho treats this file as HTML, but not as a plain text.
It happens with .DOC files as well.

You can find an example here: http://lipster.net/test.html

This problem is not only with Remote API, but in Zoho Writer web-service. However, in case of service, problem occurs only with TXT files � HTML-symbols in DOC files are shown correctly.

Please help me :)
