问题 I want to replace all emoji with '' but my regEx doesn't work. For example, content= u'?\u86cb\u767d12\U0001f633\uff0c\u4f53\u6e29\u65e9\u6668\u6b63\u5e38\uff0c\u5348\u540e\u665a\u95f4\u53d1\u70ed\uff0c\u6211\u73b0\u5728\u8be5\u548b\U0001f633?' and I want to replace all the forms like \U0001f633 with '' so I write the code: print re.sub(ur'\\U[0-9a-fA-F]{8}','',content) But it doesn't work. Thanks a lot. 回答1: You won't be able to recognize properly decoded unicode codepoints that way (as

问题 Let's say I have this 3 emojis in a string: 😀🎃👪 There are not any spaces or any other character except emojis in the string. How can I remove the last emoji in javascript? 回答1: You can do this. It will always remove the last emoji. function removeEmoji() { var emoStringArray = document.getElementById('emoji').innerHTML; var lastIndex = emoStringArray.lastIndexOf(" "); var stripedEmoStringArray = emoStringArray.substring(0, lastIndex); document.getElementById('emoji').innerHTML =

问题 What is the purpose of half- and full-width characters and what is the difference between them? I am mostly curious because validator.js (an open-source string validation library) has a couple of functions that evaluate the form of a given input: isFullWidth(str) isHalfWidth(str) isVariableWidth(str) Why might someone want to evaluate the form of a some text? Internally, the library uses this regex pattern to determine if the input is full-width: /[^\u0020-\u007E\uFF61-\uFF9F\uFFA0-\uFFDC

问题 I downloaded a dataset of facebook messages and it was formatted like this: f\u00c3\u00b8rste student It's supposed to be første student but I cant seem to decode it correctly. I tried: str = 'f\u00c3\u00b8rste student' print(str) # 'første student' str = 'f\u00c3\u00b8rste student' print(str.encode('utf-8')) # b'f\xc3\x83\xc2\xb8rste student' But it did't work. 回答1: To undo whatever encoding foulup has taken place, you first need to convert the characters to the bytes with the same ordinals

问题 As the question says, do I have to do in order to print Unicode characters to the output console? And what settings do I have to use? Right now I have this code: wchar_t* text = L"the 来"; wprintf(L"Text is %s.\n", text); return EXIT_SUCCESS; and it prints: Text is the ?. I've tried to change the output console's font to MS Mincho, Lucida Console and a bunch of others but they still don't display the japanese character. So, what do I have to do? 回答1: This is code that works for me (VS2017) -

问题 I am trying to query and display utf-8 encoded characters in a gui built on tkinter and thus tcl. However, I have found that tkinter cannot display 4-byte characters i.e. unicode codepoints greater than U+FFFF. Why is this the case? What limitations would implementing non-BMP characters have for tcl? I can't query non-BMP characters through my gui, but if they come up in a result I can copy/paste the character and see the character/codepoint through unicode-table.com despite my system not
