问题 I was working on an app, which takes input in a language called "Tamil". So in order to find the range of any particular charater in the string i have used the below code. var range = originalWord.rangeOfString("\(character)") println("\(range.location)") So this works fine except for some cases. there are some characters like this -> í , ó . // am just saying an example. So like this combination, in other languages there are several vowel diacritcs are there. If i have this word "alv`in" //

问题 I get some HTML code like the following: <new>8003,%u767E%u5723%u5E97,113734,%u4E50%u4E8B%u542E%u6307%u7EA2%u70E7%u8089%u5473,6924743915824,%u7F50,104g,3,21.57,-2.16,0,%u4E50%u4E8B,1</new> I know I can find and replace all the "%u" with "/u" in Notepad++, and then paste it into Python console to let it display correctly in Chinese characters. But how can I do it automatically in Python? 回答1: Assuming that your input string contains "percent-u" encoded chracters, we can find and decode them

问题 Most questions around reading strings from disk in Python involve codec issues. In contrast, I have a CSV file that just flat out has garbage data in it. Here's how to create an example: b = bytearray(b'a,b,c\n1,2,qwe\n10,-20,asdf') b[10] = 0xff b[11] = 0xff with open('foo.csv', 'wb') as fid: fid.write(b) Note that the second row, third column has two bytes, 0xFF , which don't represent any encoding, just a small amount of garbage data. When I try to read this with pandas.read_csv: import

问题 My application uses the unicode character \u2192 to display a right arrow within a TextView element. However, the arrow is shown at the very bottom line, but should be centered vertically: However, if I print the unicode character using the standard output, everything is fine: public class Main { public static void main(String[] args) { System.out.println("A" + Character.toString("\u2192".toCharArray()[0])); } } How I can enforce the right arrow to be centered in the TextView, too? My

问题 This question already has an answer here : How do I get the scalaz IDEA live templates working for the symbolic methods? (1 answer) Closed last year . How can I configure IDEA to automatically replace => with ⇒ and -> with → ? 回答1: Take a look at this question and answer which makes use of IntelliJ's "Live Templates", in this case scalaz mappings in XML form saved as a file rather than entered from the GUI. This, I guess, is fine with scalaz as all the unicode aliased functions and methods

问题 I found several topics of this and I found this solution: sentence=re.sub(ur"[^\P{P}'|-]+",'',sentence) This should remove every punctuation except ', the problem is it also strips everything else from the sentence. Example: >>> sentence="warhol's art used many types of media, including hand drawing, painting, printmaking, photography, silk screening, sculpture, film, and music." >>> sentence=re.sub(ur"[^\P{P}']+",'',sentence) >>> print sentence ' of course what I want is to keep the sentence

Closed 2 years ago . I need a tool that will translate the unicode string into escape characters like \u0230.
