the output it is having trouble finding the upside down equivalent to ...
If you want to have any text (really) rotated upside down or mirrored you probably should consider Latex. It is probably the easier option keeping the text format (avoiding to convert all stuff to an image), thus you can still search for (most of) the text. Please note that this will not print directly to a terminal, instead a pdf with the text placed exactly as you want (in your wildest formating's dreams) will be created.
---- file example.tex
\documentclass[40pt]{article}
\usepackage{rotating}
\begin{document}
Perlmonks
\reflectbox{Perlmonks}\\
\rotatebox{92}{Perlmonks}
\rotatebox{68}{{\bf Perlmonks}}
\reflectbox{\rotatebox{60}{Perlmonks}}
\end{document}
--- end of file example.tex
To use, (install miktex and..) run in a shell as:
pdflatex example.tex
And then simply open example.pdf with your favourite pdf's viewer
