I don't have access to that patch but if it was correct; I'm sure that it
was very costly though.
A recent attempt looked like following:
private static class RegExps { /* Formatted strings for the
fallback regular expressions were generated with the following *
Python 3 script. from unicodedata import bidirectional, category
from itertools import * condition = lambda x:
category(chr(x)).startswith("L") # adjust this uchr = lambda x:
"\\\\u%04X" % x if bidirectional(chr(x)) in ("R", "AN", "AL") else
chr(x) ranges = [] codepoints = [x for x in range(0, 0xFFFF) if
condition(x)] for _, group in groupby(enumerate(codepoints), lambda
t: t[0] - t[1]): l = list(item for (index, item) in group)
ranges += [uchr(l[0]) + ("-" if len(l) > 2 else "") + (uchr(l[-1])
if len(l) > 1 else "")] formatted = " \"[" for r in
ranges: if len(formatted) + len(r) > 99:
print(formatted + "\"") formatted = " + \""
formatted += r print(formatted + "]\";") */ private static
