Additional information:

After some debugging, I’ve determined that K9 mail is objecting to the extremely weird filename that the mooshimeter is creating for the log file. My unit is creating file names of the form:

Moosh1 “�-Log2-20171107_1531.csv

Where the characters between Moosh1 and Log2 are:

0x20,0x03,0x20,0x22,0xef,0xbf,0x2d

This is pretty weird by anyone’s file name standards. Is this normal behavior? How can I change it to A..z, 0..9 file names?

When I rename the file to something more reasonable, I can send it just fine.
