hum its not php sometimes..
The thing is that this reads RSS feeds for example, and other locak weather conditions, that will show up. and those sites aren't php. :\
saving as txt or html is not the solution.

i though got a program in c++ that converts a input file into any encoded i want.

So this is the process..
Request HTML -> save HTML to something.txt or .gs then, Call a comand EXECUTE to execute the program converter with parameters like silent( no windows) and the output name.. and the conversion encoding format.. --> then finaly read that last ffile, that is the GS format to read.

If you need that program i can give you, it took me alot to found such on the web for free..
