# Warning: No -m.map found for TS1

I'm using the cmap package, the mmap package and the textcomp package along with them and I'm getting the following error when trying to include the \copyright symbol:

Package mmap Warning: !!! No -m.cmap file found for TS1 !!!

I have a pretty basic understanding of how cmap and mmap work... can anyone explain this warning to me and tell me how to get rid of it? (I know it's just an innocent warning, but I like to brag about my TeX files compiling with none :P)

MWE:

\RequirePackage[resetfonts]{cmap}
\RequirePackage[useTeX]{mmap}

\documentclass{article}

\usepackage{textcomp}

\begin{document}

\end{document}

PS: I read that the \RequirePackage method was preferred for cmap and mmap, can't remember where though... can anyone elaborate on this matter please?

It seems from the README file of the mmap package that the TS1 encoding is not (yet) supported :

TODO: add *.cmap files for other font encodings (contributions are welcome): TS1, OT2, IL2, ...

So the package issues a warning when LaTeX finds a symbol (\copyright) that uses TS1 encoding.

<facepalm> Alright, how does one go about producing one such file? I have no problem in contributing it but I don't know where to start. –  mpr Nov 2 '11 at 12:05
@mpr I don't know but this seems to be a cookbook reference: adobe.com/content/dam/Adobe/en/devnet/font/pdfs/… pages 41 and seq. –  cjorssen Nov 2 '11 at 21:34
