unicode

问题 I am trying to return a request but it is giving me an error that there are non-unicode characters in the string. I am filtering them out but then it makes the string in unicode style which crashes the app with a badly formatted response. Here is what I am trying to do unfiltered_string = str({'location_id': location.pk, 'name': location.location_name,'address': location.address+', '+location.locality+', '+location.region+' '+location.postcode, 'distance': location.distance.mi, }) filtered

问题 I would like to save specific unicode characters to a pdf file with ggsave . Example code library(ggplot2) ggplot() + geom_point(data = data.frame(x=1, y=1), aes(x,y), shape = "\u2191") + geom_point(data = data.frame(x=2, y=2), aes(x,y), shape = "\u2020") ggsave("test.pdf", plot = last_plot()), width = 40, height = 40, units = "mm") However, when saving the .pdf the unicode characters are transformed to three dots... Attempts to fix it I tried to use the cairo_pdf device in ggsave -> didn't

问题 I am trying to open an image that has Latin characters in its name ( 113_Atlético Madrid ). I saved it by encoding its name with the PHP function rawurlencode() , so now its new name is 113_Atl%C3%A9tico%20Madrid . But when I am trying to open it by this URL for example mysite.com/images/113_Atl%C3%A9tico%20Madrid.png I got 404 error. How I can fix this issue? PHP code: if(isset($_FILES['Team'])){ $avatar = $_FILES['Team']; $model->avatar = "{$id}_".rawurlencode($model->name).".png"; if(!is

问题 Using input() takes a backslash as a literal backslash so I am unable to parse a string input with unicode. What I mean: Pasting a string like "\uXXXX\uXXXX\uXXXX" into an input() call will become interpreted as "\\uXXXX\\uXXXX\\uXXXX" but I want it read \u as a single character instead of two separate characters. Does anyone know how or if possible to make it happen? Edit: I am taking input as above and converting it to ascii such as below.. import unicodedata def Reveal(unicodeSol):

问题 I want to remove characters with encodings larger than 3 bytes. Because when I upload my CSV data to Amazon Mechanical Turk system, it asks me to do it. Your CSV file needs to be UTF-8 encoded and cannot contain characters with encodings larger than 3 bytes. For example, some non-English characters are not allowed (learn more). To overcome this problem, I want to make a filter_max3bytes funciton to remove those characters in Python3. x = 'below ð\x9f~\x83,' y = remove_max3byes(x) # y=="below

问题 I am wondering which Win32 API call is creating the files with UNICODE path. Just to make sure, I am not talking about the content here only the file path. I would appreciate if somebody would hit me with an MSDN url, my google fu failed this time. Thanks a million in advance. 回答1: See CreateFile msdn link: http://msdn.microsoft.com/en-us/library/windows/desktop/aa363858%28v=vs.85%29.aspx, if you pass a unicode string to the lpFileName parameter then the unicode version of CreateFile will be

问题 I am importing data from MS-Excel to PostgreSQL in python(2.6) using pyodbc . The problem faced is: There are characters like left single quotation mark(ANSI hex code : 0x91) , etc in the excel source. Now, when it is import into PostgreSQL using pyodbc, it terminates and gives the error DatabaseError: invalid byte sequence for encoding "UTF8": 0x91 . What I tried: I used decode('unicode_escape') for the time being. But, this cannot be done as this simply removes/escapes the concerned

问题 I'm looking to standardize some unicode text in python. I'm wondering if there's an easy way to get the "denormalized" form of a combining unicode character in python? e.g. if I have the sequence u'o\xaf' (i.e. latin small letter o followed by combining macron ), to get ō ( latin small letter o with macron ). It's easy to go the other way: o = unicodedata.lookup("LATIN SMALL LETTER O WITH MACRON") o = unicodedata.normalize('NFD', o) 回答1: As I have commented, U+00AF is not a combining macron.

问题 I would like to display emojis on my webpage in a react chat app. The plan is to give the user a list of emojis to select from. How do I use the codes like '1F683' and have them display the emoji on the page? I need to support Chrome. I am able to use css to show the emoji. <div className="smiley"></div> .smiley:after { content: "\01F683"; } I can also have a list of images and map them to the code and display an img element per emoji. Is there another way and which is the best way to do this

问题 According to the specification the characters [#x10000-#xEFFFF] are legal in XML names. However, the W3 validator says that this XML is not well-formed: <?xml version="1.0"?> <𐐀>value</𐐀> (the name of the attribute is a Unicode character #x10400). Some browsers, like Firefox, also complain about it (Chrome displays XML, IE shows a blank page). Is it an error in tools or the XML is really not well-formed? 回答1: Is it an error in tools or the XML is really not well-formed? It's well formed in
