15557	mmcif.find_template_residue() fails on Mac for template names containing '_'	Tristan Croll	Greg Couch	"Reported by Yang Lee, just confirmed by me in ChimeraX 1.8. In Windows:

`open TRP_LL from ccd`

... works correctly, but the identical command in the Mac version fails with ""Unknown CCD ligand name"". Digging into the API, I can confirm the failure happens in `mmcif.find_template_residue()` - apparently for any name containing an underscore, but only if the relevant template hasn't been downloaded. For templates that already exist in ~/Downloads/ChimeraX/CCD there is no error (I have a series of HIS_...cif templates in there, indicating that fetching of these *used* to work). Some sort of obscure Unicode issue, perhaps?"	defect	closed	moderate	1.9	Input/Output		limitation		Yang.Lee@… Eric Pettersen				all	ChimeraX
