unicode

问题 My javsacript source code is strictly ascii and I want to represent the anger symbol in a string literal. Is that possible in javascript? 回答1: JavaScript strings are effectively UTF-16, so you can write the surrogate pair using Unicode escapes: "\uD83D\uDCA2" (this is what's shown on that page for the Java source code, which also works in JavaScript). As of ES2015 (ES6), you can also write it as \u{1F4A2} rather than working out the surrogate pairs (spec). Example: Using \uD83D\uDCA2 :

问题 Is there any way to send unicode values in a cookie in expressjs. When a user is using a Spanish locale, a cookie is serialized with the user name, which can be something like "José" e.g: res.cookie('user', JSON.stringify({name: 'José'})); However in the client I get a cookie with the value: {name: 'José'} is there any way around this? The server already outputs that. 回答1: To be able to use unicode characters in a cookie, you should use an encoding scheme. encodeURIComponent() or querystring

问题 I'm reading in a text file. I've been doing it just fine with python2, but I decided to run my code with python3 instead. My code for reading the text file is: neg_words = [] with open('negative-words.txt', 'r') as f: for word in f: neg_words.append(word) When I run this code on python 3 I get the following error: UnicodeDecodeError Traceback (most recent call last) <ipython-input-14-1e2ff142b4c1> in <module>() 3 pos_words = [] 4 with open('negative-words.txt', 'r') as f: ----> 5 for word in

问题 I have a pandas dataframe with a single column that contains a unicode encoded name. import pandas as pd no_unicode = pd.Series(['Steve', 'Jason', 'Jake']) yes_unicode = pd.Series(['tea', 'caf\xe9', 'beer']) var_names = dict(no_unicode = no_unicode, yes_unicode = yes_unicode) df = pd.DataFrame(var_names) print(df) I can print the dataframe in ipython fine, but I get an error when I try to print the dataframe in Sublimetext (using py3). UnicodeEncodeError: 'ascii' codec can't encode character

问题 I have a list of unicode file paths in which I need to replace all umlauts with an English diacritic. For example, I would ü with ue, ä with ae and so on. I have defined a dictionary of umlauts (keys) and their diacritics (values). So I need to compare each key to each file path and where the key is found, replace it with the value. This seems like it would be simple, but I can't get it to work. Does anyone out there have any ideas? Any feedback is greatly appreciated! code so far: # -*-

问题 I have some perl code which deletes folders using function File::Path::rmtree. This function works successfully if the folder structure contains ascii character files/folders but fails if the folder contains Unicode character files/folders..

Here is sample code: use strict 'vars'; require File::Path; sub

问题 The company I work for is in the process of upgrading from Maximo 7.1 with Oracle 10g to Maximo 7.6 with SQL Server 2014. The program allows Chinese and thai characters in 7.1 and Oracle 10g through the front end without any issues but the new version with SQL Server 2014 replaces the Chinese/thai characters with ???. Now, I know the SQL buffs out there will say that's what happens when Unicode data is entered into a non-Unicode field (nvarchar/varchar) and this I know. But... I can change

问题 This question already has answers here : What is the meaning of the prefix N in T-SQL statements and when should I use it? (4 answers) Closed 1 year ago . In a nvarchar(512) field if i store unicode chars like this: UPDATE MYTABLE SET UNICODEFIELD = 'TﾚEﾎSￔTﾙ' when i query it i get T?E?S?T? It looks like the "unusual" chars are not considered as unicode, i would expect the "?" behavior in case of varchar , while with nvarchar it should work fine, i am expecting TﾚEﾎSￔTﾙ as output, instead of
