Alchemical Symbols: 128/128 (100.00%)

Miscellaneous Technical: 256/256 (100.00%)
Musical Symbols: 220/256 (85.94%)
Illegal division by zero at /usr/bin/ttfcoverage line 42.
Error is likely due to this font containing some blocks newer than were assigned in Unicode 6.0.0
and it also assigns some characters to reserved code points & UCN proposals for Unicode 7.*
Please add an escape subroutine(s) to allow for both the following errors;
"less than 0.00%" and ">100%"
if
{ Unicode block not found }
then
{ block-coverage = "unknown-&#percent;" }
else
{ Unicode block-size is less than code points in font }
then
{ block-coverage = "&#gt;100&#percent;" }
