I'm creating a html website using HTML, PHP and MySQL but on HTML appears some a diamond icon on characters with accent. There is some prints to help you out.  I set this meta too:  &lt;meta http-equiv="Content-Type" content="text/html;charset=utf-8"&gt;   HTML Page:    PHPMyAdmin:   PS.: This question is not a replication of other question! If it is please tell me the link because I searched the same question and nothing found!!!

I'm setting up a new server and want to support UTF-8 fully in my web application. I have tried this in the past on existing servers and always seem to end up having to fall back to ISO-8859-1.  Where exactly do I need to set the encoding/charsets? I'm aware that I need to configure Apache, MySQL, and PHP to do this — is there some standard checklist I can follow, or perhaps troubleshoot where the mismatches occur?  This is for a new Linux server, running MySQL 5, PHP, 5 and Apache 2.

Consider the following text (incidentally, part of a MySQL dump):   CREATE TABLE `table` (   `id` int(10) NOT NULL auto_increment,   `name` varchar(100) NOT NULL default '',   `description` text NOT NULL,   PRIMARY KEY  (`id`),   FULLTEXT KEY `full_index` (`name`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; /*!40101 SET character_set_client = @saved_cs_client */;   I would like to remove the FULLTEXT key, and I also want to remove the trailing comma on the line above so that the SQL remains valid.  Can anyone come up with (and explain) a sed recipe to do this?

This has been confusing me for some time. With the advent of UTF-8 as the de-facto standard in web development I'm not sure in which situations I'm supposed to use the HTML entities and for which ones should I just use the UTF-8 character. For example,   em dash (–, &amp;emdash;) ampersand (&amp;, &amp;amp;) 3/4 fraction (¾, &amp;frac34;)   Please do shed light on this issue. It will be appreciated.

Could I get an example as to how these three elements (are these called metacharacters?) differ?  I know that * means all or nothing, but I am not sure if it's the right way to think about it. On the other hand . and ? seem the same. They match one character, right?

A question from  popped up in the "Hot Network Questions" list, and I couldn't help but notice that its icon is a little bit... lacking.        Shouldn't there be some letters there or something? Maybe "Ec"? Both the main site and the meta are equally nondescript.             As pointed out by  in the comments, this is a high-DPI specific issue.     This is another one of those "shows up on normal DPI, but breaks on high DPI" bugs because  is missing the Ec, but  is not.

When editing a question with tags which contain accent marks (and likely other non-ASCII characters), the display is garbled, showing HTML escape sequences to the user:    The above screen shot is taken while editing  on my Nexus 4 with Android 5.1.1 viewing the mobile web site (not the Android app).  Although I initially discovered the issue trying to edit  on the pre-private-beta ES.SO (so likely not yet visible to many people).

I want to write something basic like "10 $US" but sometimes it makes the text look weird. It changes the font and writes italic text. And sometimes it will insert a newline. For example in my .  How can I safely insert a dollar sign?

Please how can I insert these unicode symbols in the range u2400 to u2421. They are names of control characters.  You can see them here:   I could find the package keystroke which has very nice keys, but that is not what I want.  Thanks!  -- Edited:  Quoting Marco: "The problem is to find a font that contains these characters."

When I run a particular SQL script in Unix environments, I'm am seeing a '^M' character at the end of each line of the SQL script as it is echoed to the command-line.  I don't know on which OS the SQL script was originally created.  What is causing this and how do I fix it?

Earlier today a question was asked regarding .  The top answer, at time of writing, suggests in PHP just using htmlspecialchars and mysql_real_escape_string.   My question is: Is this always enough? Is there more we should know? Where do these functions break down?

in Windows XP, when I type an apostrophe ', or  ", no character is displayed.  If I type another character, the apostrophe or dumb quote and the next character appear at the same time.  This happens with double quotes ", apostrophes ' and tilde ~ characters.  What could possibly be causing this?  This occurs in all applications I have tested - wordpad, firefox, ms word etc.

Here's the screenshot of my experience with italic text over Stack Overflow.     Basically it just wraps the word into asterisks and leaves it like this. Here on Meta I do not observe this bug.

If you try to enter a internationalized domain name as your "website" in your profile, it will be silently stripped of any non-English characters.  Ex: My webiste is  but when I try to enter that it saves it as http://linus.unnebck.se/ when it actually should display linus.unnebäck.se and link to http://linus.xn--unnebck-9wa.se/ (or just link with the ä, don't now what is the right thing to do).  As I wrote this post I also noticed that the markup ends the link at the first non-English character aswell, look at the example above.

In my long document I, sadly, have to use several accents to denote different kinds of symbols. Currently, I use primes ($x'$), hat, tilde, and overline. In addition I use two colored symbols (red colored tilde and blue $\prescript\ulcorner$), as I need further distinguishment.  Now I'd like to have no colors in my document, while I still have at least six different ways to differentiate certain symbols.  Which alternatives could I use that are easy to recognize and 'stand out', while they are different to prime/hat/tilde/overline?  EDIT: The reader should be able to see the kind of accent used even if the symbol in question is in a sub-script (possibly even a sub-sub-script).

If I try to put something like this into a question or answer  &lt;!-- &lt;br&gt;s are important here --&gt;   the first &gt; after the "br" is matched to the first &lt; before the "!--", resulting in this being displayed:     s are important here -->   This happens in both previews and actual posts. I'd say it's a bug.  HTML comments shouldn't be treated as regular HTML tags; &lt;!-- should only be matched to --&gt;.
