Where can I find an array of the unassigned Unicode code points for a particular block?
- by gitparade
At the moment, I'm writing these arrays by hand.
For example, the Miscellaneous Mathematical Symbols-A block has an entry in hash like this:
my %symbols = (
...
miscellaneous_mathematical_symbols_a => [(0x27C0..0x27CA), 0x27CC,
(0x27D0..0x27EF)],
...
)
The simpler, 'continuous' array
miscellaneous_mathematical_symbols_a => [0x27C0..0x27EF]
doesn't work because Unicode blocks have holes in them. For example, there's nothing at 0x27CB. Take a look at the code chart [PDF].
Writing these arrays by hand is tedious, error-prone and a bit fun. And I get the feeling that someone has already tackled this in Perl!
