Hi,

since you are using a filtering istream, why don't you implement your 
filter according to the tutorial? E.g.:

http://www.boost.org/doc/libs/1_42_0/libs/iostreams/doc/tutorial/multichar_filters.html

You could then add your filter to the filter chain of a filtering stream 
and you're done.

HTH
