RFC: Compile in [flt]c Unicode mappings
Message ID:
fc, lc, uc, and tc (tc is titlecase, known in Perl as ucfirst) change 
the case of their operands.  It would be relatively simple to move their 
full Unicode definitions into core, like we did in 5.20 for things like 
\w, [:xdigit:], etc,.

Part of this is a no-brainer.  It turns out that the tc definition is 
identical to the uc definition except for 89 of the million+ possible 
code points, and this number is unlikely to grow.  By separating those 
89 out, we can combine the remaining data structures for the two ops. 
It's only a little extra text-segment data to compile-in those 89 

But then it occurred to me that we might want to compile in the three 
remaining properties.  This would increase the static text segment size, 
by roughly what \w did, for each one.  And it would decrease the data 
segment should these definitions actually get used.

(The definitions for the code points 0-255 are already compiled-in.)

I just want to get a general sense from people of whether this might be 
worth pursuing
