How to URL-encode/decode SELECTED text in Notepad++

问题 There is a question here on stack overflow that answers PART of my question (see link) https://stackoverflow.com/a/17431971/2461910 Unfortunately, this solution is cumbersome, because it always encodes/decodes the ENTIRE current document. My question is: How can I change the JavaScript in that solution to only modify whatever text is SELECTED in the current document? I tried using Editor.currentView.selected , but that throws an error when the script runs. If only I could find a document

PHP处理中文真是累啊

折腾了一天的时间，才弄出点眉目来。做AJAX应用或Flash应用，提交中文内容到后台，涉及到编码解码(encode、decode)及编码格式的转换。网上的PHP端escape unescape函数建议不要用，它把中英文混合时的英文过滤掉了，我是莫名其妙了N久啊，建议用unicode_urldecode这个。再就是编码格式的转换，这主要涉及数据的存储和客户端返回，用iconv就搞定，这个函数似乎是从C++中借鉴来的。 function unicode_urldecode($url) { preg_match_all('/%u([[:alnum:]]{4})/', $url, $a); foreach ($a[1] as $uniord) { $dec = hexdec($uniord); $utf = ''; if ($dec < 128) { $utf = chr($dec); } else if ($dec < 2048) { $utf = chr(192 + (($dec - ($dec % 64)) / 64)); $utf .= chr(128 + ($dec % 64)); } else { $utf = chr(224 + (($dec - ($dec % 4096)) / 4096)); $utf .= chr(128 + ((($dec % 4096) - (

Decoding international chars in AppEngine

问题 I'm making a small project in Google AppEngine but I'm having problems with international chars. My program takes data from the user through the url "page.html?data1&data2..." and stores it for displaying later. But when the user are using some international characters like åäö it gets coded as %F4, %F5 and %F6. I assume it is because only the first 128(?) chars in ASCII table are allowed in http-requests. Is there anyone who has a good solution for this? Any simple way to decode the text?

How to “URL decode” a string in Emacs Lisp?

阅读更多关于 How to “URL decode” a string in Emacs Lisp?

问题 I've got a string like "foo%20bar" and I want "foo bar" out of it. I know there's got to be a built-in function to decode a URL-encoded string (query string) in Emacs Lisp, but for the life of me I can't find it today, either in my lisp/ folder or with google. Anybody remember what it's called? 回答1: org-link-unescape does the job for very simple cases ... w3m-url-decode-string is better, but it isn't built in and the version I have locally isn't working with Emacs 23. 回答2: url-unhex-string

Here is the code which i use; $message="The user name you provided is already in our database"; redirect('admin/add_user/'.$message); Here is
