Indeed! And printing black boxes won't help a lot either...

There is the simple solution to check in the definition of the ligatures
if the ligatures really exist (in the encoding, not the avialable
characters). This works fine and makes a complex font-dependent job very
managable via fontinst.
  \if \tty y \else
      \ligature{LIG}{\lc{T}{t}}{\lclig{CT}{ct}} \fi
      \ligature{LIG}{\lc{H}{h}}{\lclig{CH}{ch}} \fi
      \ligature{LIG}{\lc{K}{k}}{\lclig{CK}{ck}} \fi
  \comment{The letter `{c}'.}
