ios - Inconsistent Unicode Emoji Glyphs/Symbols -

-

i've been trying make use of unicode symbols astrology in products both apple , ios. i'm getting inconsistent results, shown here:

image of astrological symbols in table

most of these coming out like, reason taurus symbol appearing 1 way on first line, following moon, , different way, emoji-like purple button, when follows mars. these results consistent different symbols , across apple hardware; here's screen capture phone showing same problem other signs - scorpio comes out right, libra , cancer buttons.

more symbols in clip iphone

the strings extremely straightforward; "moon taurus" in first image \u263d moon, \u2649 taurus, assembled [nsstring stringwithformat:@"%@%@", @"\u263d", @"\u2649"]. "mars taurus" image same, \u2642 mars. string formatting identical in different cells of osx table, , in ios attributedstring.

any idea makes these symbols appear 1 way sometimes, , way other times?

unicode uses variation sequences select between different renderings code points—listed in standardizedvariants.txt file. in case, astrological symbols have both "text style" , "emoji style" variants selected between u+feoe (text style) or u+fe0f (emoji style) following code point:

u+2650 u+fe0e: ♐︎

u+2650 u+fe0f: ♐️

note correct interpretation of variation selector depends on support both application/framework , fonts being used. on chrome (42) there doesn't appear difference between examples above, on safari (8) distinct.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
