unicode-escapes

问题 This question already has an answer here : ES6: Bad character escape sequence creating ASCII string (1 answer) Closed 3 years ago . If I want to print a unicode Chinese character in ES6/ES2015 javascript, I can do this: console.log(`\u{4eb0}`); Likewise, if I want to interpolate a variable into a template string literal, I can do this: let x = "48b0"; console.log(`The character code is ${ x.toUpperCase() }.`); However, it seems that I can't combine the two to print a list of, for example, 40

问题 I have a Unicode file that needs to be exported to database(Vertica). The column delimiter is CTRL+B, record delimiter is newline(\n). Whenever there is a newline within a column value, CTRL+A is used as escape character. When I use BufferedReader.readLine() to read this file, the records with ID's 2 and 4, are read as two records. Whereas I want to read them as a single whole record as given in output. Here is the example input file. | stands for CTRL+B and ^ stands for CTRL+A. Input ID|Name

问题 I have a list of Unicode character codes that I would like to output with rumoji . Here's the code I'm using to iterate over my data. require "rumoji" # this works puts Rumoji.decode("\u{1F600}") # feed some data data = [ "1F600", "1F476", "1F474" ] data.each do |line| # this doesn't work puts Rumoji.decode("\u{#{line}}") puts Rumoji.decode("\u{" + line + "}") end I'm not sure how I can use variable names inside the escaped string. 回答1: One can not use \u along with string interpolation,

问题 I've been playing around with swing for some time and decided to check out FX now. So far I'm finding it a lot easier and more fun to work with as compared to swing but I've run into a small speed bump and after hours of looking around I just can't find a solution. I am unable to use \u when I try to add it through the fxml file It works fine if I don't use the fxml but I want to use the scene builder as it is more convenient. Here's the small piece of code: <?xml version="1.0" encoding="UTF

问题 Is there any alternative function/solution of the ChrW() which accepts value not in range is -32768–65535 like for character code 􀂇 which leads to "􀂇". Using ChrW() gives error "Invalid procedure call or argument" So I want an alternative solution to convert the charactercode to the actual character. Code: Function HTMLDecode(sText) Dim regEx Dim matches Dim match sText = Replace(sText, """, Chr(34)) sText = Replace(sText, "<" , Chr(60)) sText = Replace(sText, ">" , Chr(62)) sText = Replace

问题 I am, for the sake of testing my web app, pasting some random characters from /dev/random into my web frontend. This line throws an error: print repr(comment) import html5lib print html5lib.parse(comment, treebuilder="lxml") 'a\xef\xbf\xbd\xef\xbf\xbd\xc9\xb6E\xef\xbf\xbd\xef\xbf\xbd`\xef\xbf\xbd]\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd2 \x14\xef\xbf\xbd\xc7\xbe\xef\xbf\xbdy\xcb\x9c\xef\xbf\xbdi1O\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbdZ\xef\xbf\xbd.\xef\xbf\xbd\x17^C'

问题 I got JSon string with escape unicode symbols \u041e\u043f\u043e\u0440\u0430 \u0448\u0430\u0440\u043e\u0432\u0430\u044f VW GOLF I know that 4 digits after \u are the hex code of unicode character. So here's how I decoded those strings ALTER FUNCTION dbo.Json_Unicode_Decode(@escapedString VARCHAR(MAX)) RETURNS VARCHAR(MAX) AS BEGIN DECLARE @pos INT = 0, @char CHAR, @escapeLen TINYINT = 2, @hexDigits TINYINT = 4 SET @pos = CHARINDEX('\u', @escapedString, @pos) WHILE @pos > 0 BEGIN SET @char =

问题 I am having an issue URL decoding a UTF-8 string in Java that is encoded either with Javascript or Actionscript 3. I've set up a test case as follows: The string in question is Produktgröße When I encode with JS/AS3 I get the following string: escape('Produktgröße') Produktgr%F6%DFe When I unescape this with JS I get no change unescape('Produktgr%F6%DFe') Produktgr%F6%DFe So, by this I assume that JS isn't encoding the string properly?? The following JSP produces this outupt <%@page import=

问题 I have few strings like "12.10 On-Going Submission of ""Made Up"" Samples." 10. PRODUCT STANDARDS; APPROVAL. which I render as JSON in grails. The quotes and any other possible special characters are giving me trouble i.e they make the JSON invalid when returning a response from the REST service. How do I solve this? I have tried few things but nothing seems to work: //text: java.net.URLEncoder.encode(artifact.text, "UTF-8"), //Loses the original format //text : artifact.text

问题 I'm adding HTML Tag Attributes to a section in a Gantry 5 layout, using the section's settings. But any special characters are rendered as Unicode Hex Character Codes in the resultant HTML. So adding the tag data-0 to the section g-mainbottom1 with the attribute background-position: 50% 100px results in this div: <section id="g-mainbottom1" data-0="background-position: 50% 100px;"> rather than the desired <section id="g-mainbottom1" data-0="background-position: 50% 100px;"> Assuming there's
