UTF-8, UTF-16, and UTF-32

@Urkle is technically correct because mapping the full range of UTF32/LE/BE includes U-00200000 - U-7FFFFFFF even though Unicode v6.3 ends at U-0010FFFF inclusive. Here's a nice breakdown of how to enc/dec 5 and 6 byte utf8: lists.gnu.org/archive/html/help-flex/2005-01/msg00030.h...
How do I match any character across multiple lines in a regular expression?
...opped using (?-s). A modified group can be used to only affect a specified range of a regex pattern (e.g. Delim1(?s:.*?)\nDelim2.* will make the first .*? match across newlines and the second .* will only match the rest of the line).
POSIX note:
In non-POSIX regex engines, to match any char, [\s\S...
How to make child process die after parent exits?
...death signal of the calling process to arg2 (either a signal value in the range 1..maxsig, or 0 to clear). This is the signal that the calling process will get when its parent dies. This value is cleared for the child of a fork(2) and (since Linux 2.4.36 / 2.6.23) when executing a set-use...

Why does 0.ToString(“#.##”) return an empty string instead of 0.00 or at least 0?
...decimal point and the rightmost '0' after the decimal point determines the range of digits that are always present in the result string.
The "00" specifier causes the value to be rounded to the nearest digit preceding the decimal, where rounding away from zero is always used. For example, formatti...
Python 3.x rounding behavior
...ng == None:
rounding = ROUND_HALF_UP
place = '1.'
for i in range(places):
place = ''.join([place, '0'])
return dec(number).quantize(dec(place), rounding=rounding)
Hope this helps,
