special-characters

I'm having a problem with htmlentities() $txt = "árbol"; echo $txt; // outputs: árbol echo htmlentities($txt); // outputs: árbol (árbol) The second echo should output árbol (á) I'm using utf-8: <meta charset="utf-8"> What's going on? Thank you! You have to set the third parameter of htmlentities() which tells the charset to use. Because of you don't set it, the default is used and the default is ISO-8859-1, not UTF-8. Like htmlspecialchars(), it takes an optional third argument charset which defines character set used in conversion. Presently, the ISO-8859-1 character set is used as the

I want to send a user's entry to google's geocode API. In doing so, I detected a problem. When I send the user input (e.g. "köln+Germany") through my script to the api in Firefox it works great. In Internet Explorer however it's not working. Here's the exempt of my code that's enough to show the problem: header('Content-type: text/html; charset=UTF-8'); header('Cache-Control: no-cache, must-revalidate'); $loc = urlencode($_GET['loc']); echo $address = "http://maps.googleapis.com/maps/api/geocode/json?address=$loc&sensor=false"; The output ($address) in Firefox is: http://maps.googleapis.com

I'm in the process of adding various physics equations to a website. There are several special characters I've needed to add, and I haven't been able to find some of them (for instance, I need to add a curled "E" to denote energy density, and I need to add an H with the '^' symbol on top to denote the Hamiltonian operator). Thus, I was wondering if anyone has compiled a table of all the various HTML special characters (such as ħ for h-bar, which equals h/2PI). If so, a link would be much appreciated! Thanks! How about this, from the w3 org: http://dev.w3.org/html5/html-author/charref With just

For example, I need everything in between the two square brackets. File1 [Home sapiens] [Mus musculus 1] [virus 1 [isolated from china]] So considering the above example, I need everything in between the first and last square brackets. Regular expressions are the most flexible option. For another approach, you can try string's partition and rpartition methods: >>> s = "[virus 1 [isolated from china]]" >>> s.partition('[')[-1].rpartition(']')[0] 'virus 1 [isolated from china]' You can use a greedy regex: re.search(r'\[(.*)\]', your_string).group(1) Given your sample input, it looks like every

I have a text file that is tab-delimited. How can I separate this string into substrings for an array by detecting the tabs? CD.. string s = "123\t456\t789"; string[] split = s.Split('\t'); If you use String.split() you can split the String around any regular expression, including tabs. The regex that matches tabs is \t, so you could use the following example; String foo = "Hello\tWorld"; String[] bar = foo.split("\t"); Which would return a String array containing the words Hello and World Just use the String.Split method and split on tabs (so probably first one split on newlines to get the

For example: public enum Unit{ KW, kV, V, Hz, %V } In this case % is a special character. So, how can I put this char in a enum? Enum members shouldn't be used for user interface display purposes. They should be mapped to a string in order to get displayed. You can create a string array (or a dictionary) that maps each enum member to a string for user interaction. That said, to answer your question directly, you can use \uxxxxV were xxxx is the hexadecimal number representing the Unicode code point for % . This is far from recommended. As Henk points out, this won't work for % as it's not in
