iOS - Unicode numeric value of individual characters in a string

由 我们两清 提交于 2019-12-25 04:05:49
问题 For Objective-C in iOS: If I have a string how could I read the unicode numeric value of an individual character? For example if my string was: "∆" That unicode character is U+0394, so how could I read the string, figure out the "0394" then create a new string with say 100 added to that value, so the new string would be the character U+0494 or "ҕ" Thanks! 回答1: First, there is a fallacy in your logic. ∆ + 100 != ҕ . Unicode is evaluated in base-16 (hex), so '∆' is actually equal to 916 in

How to pass a latin1 charset associative array from php to javascript?

由 为君一笑 提交于 2019-12-25 03:54:25
问题 The problem is that I have latin1 charset in db. The default output is utf-8 in php. even when i am using php iconv, it returns null as the new string is supposedly already utf-8. Converting DB would need downtime. I cant use json_encode because the string is malformed utf-8 containing �. I need an alternative to temporarily fix the issue without having to migrate the db. I need to transfer the associative array back to JS. I am using Ajax for getting the data. 回答1: You could convert the

问题 I have an issue of passing the ? and = through my url since I am using drupal (although i think it doesn't matter drupal or static site). Each media content type I have needs a path of localhost/media/video?open=?cbox10 Pathauto module has this for each media asset content type. media/videos?open=?cbox[nid] The node url then looks like http://localhost/media-gallery/images%3Fopen%3D%3Fcbox14 Let me know if I'm wrong but i believe I need to now encode/decode the url using php.

How to convert special characters in HTML using PHP?

由 我的梦境 提交于 2019-12-25 03:19:07
问题 Im looking to convert special characters like smart quotes to HTML entities but without converting other HTML markup because I need HTML markup to work. For example, convert <div>NVH “noise”</div> to <div>NVH “noise” issues<div> Its strange that if I log this on my local environment I get “noise” with smartquotes but on server I got ?noise?. My local runs LAMP with php56. server ran 54 and 55. I upgraded to 56 still no luck. I think either something in php configuration or among other things.

Set the default encoding to UTF-8 for all JSPs without using @page directives

由 谁说我不能喝 提交于 2019-12-25 03:06:06
问题 What I would like to avoid is specifying a page directive at the beginning of every JSP. As I understand, without the following line, the default for the Content-Type for the page will be set to "text/html;charset=ISO-8859-1". <%@ page contentType="text/html; charset=UTF-8" %> Is there a configuration option that does the same thing without having to explicitly set the charset for every single JSP file in an application? 回答1: You can add the following to web.xml <jsp-config> <jsp-property
