vte uses strings, and has a partial implementation of code to read a 
termcap entry and interpret the function-keys defined there.  xterm 
doesn't use strings (except for a more-complete feature to interpret 
terminfo/termcap entries, likewise for the function-keys).  Reading both 
sources might be educational.
