Thank you for noticing that!

I was aware that glibc has a problem with defining width of unassigned
characters, therefore I used 

 for key in list(range(0xD7B0, 0xD7FC)):

instead of 

 for key in list(range(0xD7B0, 0xD800)):

because D7FC and D7FF are undefined and localedef gave me errors
when I included them. Surprisingly localedef did not give  errors for the
unassigned D7C7‥D7CA ...

I had checked the range manually and thought all characters
from D7B0 to D7FB were assigned, but apparently I missed D7C7‥D7CA.

I improved the generator script a bit to omit the unassigned characters,
if these get defined in future, the script would add them.
