utf-8

问题 I am trying to convert an encoded url with german Umlaute into a string with those Umlaute. Here is an example of an encoded string = 'K%C3%B6nnen'. I would like to convert it to 'Können' When I use urllib.unquote(a) I get this returned: 'K\xc3\xb6nnen' \xc3\xb6 I found out is a utf literal. How can I convert this to an ö ? I find that if I use the print function it converts it correctly, but I cannot figure out how to get a function to return this value? Any ideas? 回答1: With decode("utf-8")

问题 I am trying to create a news report app from a Wordpress site using REST API but it is encoded in UTF-8. I am new in Dart, all I know is that I can decode Utf-8 just by an array of characters not by giving a string (as an input). Then how can I decode a string in Utf-8 for my app? child: new Text(posts[index]["title"]['rendered'], style: TextStyle( fontSize: 21, fontWeight: FontWeight.bold, ), textAlign: TextAlign.center), ), new Padding( padding: EdgeInsets.all(10.0), child: new ListTile(

问题 Folks, I want to sort following nested collection by string alphabeticaly : $collection = collect([ ["name"=>"maroon"], ["name"=>"zoo"], ["name"=>"ábel"], ["name"=>"élof"] ])->sortBy("name"); I would expect : 1=> "ábel" 2=> "élof" 3=> "maroon" 4=> "zoo" I got instead : 1=> "maroon" 2=> "zoo" 3=> "ábel" 4=> "élof" I seen some PHP threads for this, but I am curious if there is any Laravel workaround for this. Thanks. 回答1: Here's a Solid way to do it: $blank = array(); $collection = collect([ [

问题 When I run below code with two different project I get different outputs.

问题 I get UTF8 text from a database, and I want to show only the first $len characters (finishing in a word). I've tried several options but the function still doesn't work because of special characters (á, é, í, ó, etc). Thanks for the help! function text_limit($text, $len, $end='...') { mb_internal_encoding('UTF-8'); if( (mb_strlen($text, 'UTF-8') > $len) ) { $text = mb_substr($text, 0, $len, 'UTF-8'); $text = mb_substr($text, 0, mb_strrpos($text," ", 'UTF-8'), 'UTF-8'); ... } } Edit to add an

问题 I am aware that similar questions have been asked before, but we need a more definitive answer. Is it safe to update MySQL tables encoded in utf8 to utf8mb4 in all cases . More specifically, even for varchar fields with strings generated using for example (in Java): new BigInteger(130, random).toString(32) From our understanding utf8mb4 is a superset of utf8 so our assumption would be that everything should be fine, but we would love some input from more MySQL superusers. 回答1: How the data

问题 C++20 added char8_t and std::u8string for UTF-8. However, there is no UTF-8 version of std::cout and OS APIs mostly expect char and execution character set. So we still need a way to convert between UTF-8 and execution character set. I was rereading a char8_t paper and it looks like the only way to convert between UTF-8 and ECS is to use std::c8rtomb and std::mbrtoc8 functions. However, their API is extremely confusing. Can someone provide an example code? 回答1: At present, std::c8rtomb and

问题 please help! I am using sqlite3 in ipython notebook to create an SQL database. I think I have successfully created the database, but when I go to look at it I am receiving an encoding UTF8 error. Here is my code: import sqlite3 conn=sqlite3.connect('example.db') c=conn.cursor() c.execute('''DROP TABLE PROFILE''') c.execute('''CREATE TABLE PROFILE ( FIRSTNAME TEXT PRIMARY KEY unique NOT NULL, LASTNAME TEXT NOT NULL, EMAILADDRESS TEXT NOT NULL, PASSWORD TEXT NOT NULL, CURRENTJOBTITLE TEXT NOT

问题 I'm pulling data from a file (in this case an exim mail log) and often it saves characters in an escaped octal sequence like \NNN where 'N' represents an octal value 0-7. This mainly happens when the subject is written in non-Latin characters (Arabic for example). My goal is to find the cleanest way to convert these octal characters to display correctly in my utf-8 enabled terminal, specifically in 'less' as there is the potential for lots of output. The best approach I have found so far is

问题 I'm kinda confused about unicode characters codepoints conversion to UTF-16 and I'm looking for someone who can explain it to me in the easiest way possible. For characters like "𐒌" we get; d801dc8c --> UTF-16 0001048c --> UTF-32 f090928c --> UTF-8 66700 --> Decimal Value So, UTF-16 hexadecimal value converts to " 11011000 00000001 11011100 10001100 " which is " 3624000652 " in decimal value, so my question is how do we got this value in hexadecimal?? and how can we convert it back to the
