unicode text file

[Junaid]

I want to do replacements in a utf-8 text file. example

f=open("test.txt","r") #this file is uft-8 encoded

raw = f.read()
txt = raw.decode("utf-8")

txt.replace{'English', ur'ഇംഗ്ലീഷ്') #replacing raw unicode string,
but not working

f.write(txt)
f.close()
f.flush()


please, help me

thanks
