UnicodeEncodeError writing WaveFront OBJ

[arik@…]

The following bug report has been submitted:
Platform:        Darwin-17.7.0-x86_64-i386-64bit
ChimeraX Version: 0.7 (2018-07-31)
Description
Was saving out to OBJ format. Note: objects were clipped with the clip rotate tool before hand. Don't know if that matters. Intending to import into Cinema 4D, in which other attempts weren't able to be opened. STL worked. Thank you!

Fixed.

The atom distance labels caused the error saving OBJ format because the label text contained a non-ascii Angstrom symbol.
