symbol used in word is converted to normal text?

Question

In my word I have a symbol (alpha),style as symbol and font size 11. When I read the word in .Net using openxml(wml), the symbol is changed to normal text a. How to handle this?

Input criteria of .70.

<w:r w:rsidR="007445E8" xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main"><w:t xml:space="preserve"> </w:t></w:r><w:r xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main"><w:t xml:space="preserve">criteria of </w:t></w:r><w:r w:rsidRPr="007445E8" xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main"><w:rPr><w:rStyle w:val="Symbol" /><w:highlight w:val="yellow" /></w:rPr><w:t>a</w:t></w:r><w:r xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main"><w:rPr><w:rStyle w:val="Symbol" /></w:rPr><w:t> &gt; </w:t></w:r>

I except a code to read the symbols as it is in the word.
