remove some junk characters

Dunno what Â is, but it's not a µ. Maybe we should revert to us as an approximation for microseconds and um for micrometers because those are easy to type/display in 7-bit ASCII.

Thomas,
I suggest NOT merging this. Depending on how the log file is displayed (cat, more, vi, nano, etc.), µs will display as µs or µs. I have a newer version of capture.cpp that does a #define for the value. As @ckuethe said, I suggest we simply use "us". "um" should also be used for the pixel size in micrometers.

Hang on a moment, I'll update this to us and um.

Looks good Chris. Thanks for making the changes.
Suggested change: change the "um" for Pixel Size to "microns", since that's what you see in all the literature for pixel size. Plus, not everyone will know what "um" is (at least I didn't...).

Thomas, this looks good to me.
Chris, thanks for making the change.
