问题 What is the difference between encoding utf-8 and utf8 (if there is any)? Given the following example: u = u'€' print('utf-8', u.encode('utf-8')) print('utf8 ', u.encode('utf8')) It produces the following output: utf-8 b'\xe2\x82\xac' utf8 b'\xe2\x82\xac' 回答1: There's no difference. See the table of standard encodings. Specifically for 'utf_8' , the following are all valid aliases: 'U8', 'UTF', 'utf8' Also note the statement in the first paragraph: Notice that spelling alternatives that only

问题 I need to read in a standard ascii style string with unicode escaping and convert it into a std::string containing the utf8 encoded equivalent. So for example "\u03a0" (a std::string with 6 characters) should be converted into the std::string with two characters, 0xce, 0xa0 respectively, in raw binary. Would be most happy if there's a simple answer using icu or boost but I haven't been able to find one. (This is similar to Convert a Unicode string to an escaped ASCII string, but NB that I

问题 I am trying to include some symbols into a div using JavaScript. It should look like this: x ∈ &reals; , but all I get is: x ∈ &reals; . var div=document.getElementById("text"); var textnode = document.createTextNode("x ∈ &reals;"); div.appendChild(textnode); <div id="text"></div> I had tried document.getElementById("something").innerHTML="x ∈ &reals;" and it worked, so I have no clue why createTextNode method did not. What should I do in order to output the right thing? 回答1: You are

问题 I have this vbscript code: Set fs = CreateObject("Scripting.FileSystemObject") Set ts = fs.OpenTextFile("tmp.txt", 2, True) for i = 128 to 255 s = chr(i) if lenb(s) <>2 then wscript.echo i wscript.quit end if ts.write s next ts.close On my system, each integer is converted to a double byte character: there are no numbers in that range that cannot be represented by a character, and no number requires more than 2 bytes. But when I look at the file, I find only 127 bytes. This answer: https:/

问题 Pretty much as the title says. Rendering all of the unicode format correctly what with composite characters and characters that affect other characters and ligatures is really hard, I understand that. We have fonts that seem to be designed for maximum Unicode symbol support(Symbola, Code2001, others) and specialized fonts for certain planes or character ranges(BabelStone Han, others). I don't know much about the underlying technical details for fonts. Is there a maximum size? Is it a

问题 I am trying to create a CSV of data from a MySQL RDB to move it over to Amazon Redshift. However, one of the fields contains descriptions and some of those descriptions contain the '’' character, or the right single quotation mark. before when I would run the code, it would give me UnicodeEncodeError: 'charmap' codec can't encode character '\x92' in position 62: character maps to <undefined> I then tried using REPLACE to attempt to get rid of the right single quotation marks. db = pymysql

问题 In Python 3, I'd like to be able to use re.sub() in an "accent-insensitive" way, as we can do with the re.I flag for case-insensitive substitution. Could be something like a re.IGNOREACCENTS flag: original_text = "¿It's 80°C, I'm drinking a café in a cafe with Chloë。" accent_regex = r'a café' re.sub(accent_regex, 'X', original_text, flags=re.IGNOREACCENTS) This would lead to "¿It's 80°C, I'm drinking X in X with Chloë。" (note that there's still an accent on "Chloë") instead of "¿It's 80°C, I
