We should use whatever trim() uses, I think.

Hi Andrei,
One more related question: What about for any leading whitespace with
numeric strings, like in zend_u_strtol()? Is u_isspace() needed,
or are
only the ASCII-equivalents (0x20, 9-13 [\t, \n, \v, \f, \r]) allowed?
Thanks again,
Matt

Hi Andrei, et al.,
I was just looking at README.UNICODE, regarding interpretation of
numbers:
"we restrict numbers to consist only of ASCII digits," and "Numeric
strings
are supposed to adhere to the same rules." Is it correct to take
that to
mean only UChar's with values from '0'-'9'/0x30-0x39 (and 'a'-'z'
equivalents for bases > 10)?
Correct.
I ask because in zend_u_strtol(), HANDLE_U_NUMERIC() for array
keys, etc.,
the u_digit() function is used, which also allows non-ASCII, higher-
value
digit characters, doesn't it? But then in is_numeric_unicode(),
when
checking for hex numbers, the ASCII values '0' and 'x' are used,
which is
what I'd expect after reading README.UNICODE.
You're correct here again, u_digit() should not be used there.
