Getting Extra space while converting to Text using XSLT FO

Hi ALl,
I am giving Text in my XSL in <fo:block> and doing that XSLT to generate
Text file. But its giving extra space in between the words.
This is also not consistent between all words. How to over come this
problem? Below is formatting file which I am using.
I have posted this earlier but its not coming in list.
Thanks
