Encode lcms files as utf-8

The diff isn't well displayed in Rietveld, and I had to do some interpretation
here, as it wasn't clear what code page these files were pretending to use.
The left quotes were 0x92, the right quote + \n had been converted to ?, and
the negative infinity was 0x96. (I assume maybe Mac something.)

In any case, I tried to interpret the comments and make them something sensible.
In the worst case, it's "only" comments that are broken, as no actual code was
modified.
