url-encoding

Im trying to figure out how to extract the lat/long of the start/end in a google maps directions link that looks like this: https://www.google.com/maps/preview#!data=!1m4!1m3!1d189334!2d-96.03687!3d36.1250439!4m21!3m20!1m4!3m2!3d36.0748342!4d-95.8040972!6e2!1m5!1s1331-1399+E+14th+St%2C+Tulsa%2C+OK+74120!2s0x87b6ec9a1679f9e5%3A0x6e70df70feebbb5e!3m2!3d36.1424613!4d-95.9736986!3m8!1m3!1d189334!2d-96.03687!3d36.1250439!3m2!1i1366!2i705!4f13.1&fid=0 Im guessing the "!" is a separator between variables followed by XY where x is a number and y is a lower case letter, but can not quite figure out how

I am trying to encode and store, and decode arguments in Python and getting lost somewhere along the way. Here are my steps: 1) I use google toolkit's gtm_stringByEscapingForURLArgument to convert an NSString properly for passing into HTTP arguments. 2) On my server (python), I store these string arguments as something like u'1234567890-/:;()$&@".,?!\'[]{}#%^*+=_\\|~<>\u20ac\xa3\xa5\u2022.,?!\'' (note that these are the standard keys on an iphone keypad in the "123" view and the "#+=" view, the \u and \x chars in there being some monetary prefixes like pound, yen, etc) 3) I call urllib.quote

I'm trying to understand the structure of a URL, and I'm seeing a lot of %2C . I'm guessing this is a result of some encoding. What does that stand for? Neverever Check out http://www.asciitable.com/ Look at the Hx , (Hex) column; 2C maps to , Any unusual encoding can be checked this way +----+-----+----+-----+----+-----+----+-----+ | Hx | Chr | Hx | Chr | Hx | Chr | Hx | Chr | +----+-----+----+-----+----+-----+----+-----+ | 00 | NUL | 20 | SPC | 40 | @ | 60 | ` | | 01 | SOH | 21 | ! | 41 | A | 61 | a | | 02 | STX | 22 | " | 42 | B | 62 | b | | 03 | ETX | 23 | # | 43 | C | 63 | c | | 04 | EOT

I have a file with the following path : D:/bar/クレイジー・ヒッツ！/foo.abc I am parsing the path from a XML file and storing it in a variable called path in the form of file://localhost/D:/bar/クレイジー・ヒッツ！/foo.abc Then, the following operations are being done : path=path.strip() path=path[17:] #to remove the file://localhost/ part path=urllib.url2pathname(path) path=urllib.unquote(path) The error is : IOError: [Errno 2] No such file or directory: 'D:\\bar\\\xe3\x82\xaf\xe3\x83\xac\xe3\x82\xa4\xe3\x82\xb8\xe3\x83\xbc\xe3\x83\xbb\xe3\x83\x92\xe3\x83\x83\xe3\x83\x84\xef\xbc\x81\\foo.abc' Update 1 : I am

The signature of the String method for percent-escaping is: func addingPercentEncoding(withAllowedCharacters: CharacterSet) -> String? (This was stringByAddingPercentEncodingWithAllowedCharacters in Swift 2.) Why does this method return an optional? The documentation says that the method returns nil “if the transformation is not possible,” but it's unclear under what circumstances the escaping transformation could fail: Characters are escaped using UTF-8, which is a complete Unicode encoding. Any valid Unicode character can be encoded using UTF-8, and thus can be escaped. I thought perhaps the

I'm trying to put a Twitter share link in an email. Because this is in an email I can't rely on JavaScript, and have to use the "Build Your Own" Tweet button. For example, sharing a link to Google: <a href="http://www.twitter.com/share?url=http://www.google.com/>Tweet</a> This works fine. The problem I'm having is when the URL has a query string. <a href="http://www.twitter.com/share?url=http://mysite.org/foo.htm?bar=123&baz=456">Tweet</a> URLs with query strings confuse Twitter's URL shortening service, t.co. I've tried URL encoding this in various ways and cannot get anything to work. The

I have an instance of Apache Tomcat 6.x running, and I want it to interpret the character set of incoming URLs a little more intelligent than the default behavior. In particular, I want to achieve the following mapping: So%DFe => Soße So%C3%9Fe => Soße So%DF%C3%9F => (error) The bevavior I want could be described as "try to decode the byte stream as UTF-8, and if it doesn't work assume ISO-8859-1". Simply using the URIEncoding configuration doesn't work in that case. So how can I configure Tomcat to encode the request the way I want? I might have to write a Filter that takes the request

Here's an example: https://drive.google.com/viewerng/viewer?embedded=true&url=http://journals.plos.org/plosone/s/file?id=wjVg/PLOSOne_formatting_sample_main_body.pdf The url parameter, http://journals.plos.org/plosone/s/file?id=wjVg/PLOSOne_formatting_sample_main_body.pdf , is not encoded. It contains reserved characters, like the colon, slashes, and question mark. Why does this still work? And why bother encoding if it works without it? unor The reserved characters of an URI are mostly used as delimiters -- it doesn’t mean that they may not be used, it only means that they have a special
