php - Removing unicode from string -


i have following php string:

\ud83c\udf38owner ig: deidarasss\n\ud83c\udf38free ongkir banda aceh dan lhokseumawe\n\u27a1 testimoni: #testydfs\n\ud83d\udcf1line: darafitris\nsold=delete\nclose  \ud83d\ude0d\ud83d\ude03

i wanted strip out unicode string, how can so?

i have tried following:

 private static function removeemoji($text) {         $clean_text = "";          // match emoticons         $regexemoticons = '/[\x{1f600}-\x{1f64f}]/u';         $clean_text = preg_replace($regexemoticons, '', $text);          // match miscellaneous symbols , pictographs         $regexsymbols = '/[\x{1f300}-\x{1f5ff}]/u';         $clean_text = preg_replace($regexsymbols, '', $clean_text);          // match transport , map symbols         $regextransport = '/[\x{1f680}-\x{1f6ff}]/u';         $clean_text = preg_replace($regextransport, '', $clean_text);          // match miscellaneous symbols         $regexmisc = '/[\x{2600}-\x{26ff}]/u';         $clean_text = preg_replace($regexmisc, '', $clean_text);          // match dingbats         $regexdingbats = '/[\x{2700}-\x{27bf}]/u';         $clean_text = preg_replace($regexdingbats, '', $clean_text);          return $clean_text;     }

but doesn't help

to remove occurrences of \u.... string $text, follows:

$text = preg_replace('/\\\\u[0-9a-f]{4}/i', '', $text);

this uses regular expression find these occurrences , replace of them empty string.

alternatively, replace occurrences of \u.... characters represent, do:

$text = json_decode('"' . str_replace('"', '\"', $text) . '"');

this wraps text in double quotes, escaping double quotes within, makes valid json string. \u valid json escape code, suffices decode json actual characters.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
