 ### UTF-8 at the PHP level
 
-The basic [string operations](http://php.net/manual/en/language.operators.string.php), like concatenating two strings and assigning strings to variables, don't need anything special for UTF-8. However most [string functions](http://php.net/manual/en/ref.strings.php), like [`strpos()`](http://php.net/manual/en/function.strpos.php) and [`strlen()`](http://php.net/manual/en/function.strlen.php), do need special consideration. These functions often have an `mb_*` counterpart: for example, [`mb_strpos()`](http://php.net/manual/en/function.mb-strpos.php) and [`mb_strlen()`](http://php.net/manual/en/function.mb-strlen.php). Together, these counterpart functions are called the [Multibyte String Functions](http://php.net/manual/en/ref.mbstring.php). The multibyte string functions are specifically designed to operate on Unicode strings.
+The basic string operations, like concatenating two strings and assigning strings to variables, don't need anything special for UTF-8. However most string functions, like `strpos()` and `strlen()`, do need special consideration. These functions often have an `mb_*` counterpart: for example, `mb_strpos()` and `mb_strlen()`. Together, these counterpart functions are called the Multibyte String Functions. The multibyte string functions are specifically designed to operate on Unicode strings.
 
-You must use the `mb_*` functions whenever you operate on a Unicode string. For example, if you use [`substr()`](http://php.net/manual/en/function.substr.php) on a UTF-8 string, there's a good chance the result will include some garbled half-characters. The correct function to use would be the multibyte counterpart, [`mb_substr()`](http://php.net/manual/en/function.mb-substr.php).

 The hard part is remembering to use the `mb_*` functions at all times. If you forget even just once, your Unicode string has a chance of being garbled during further processing.
 
 Not all string functions have an `mb_*` counterpart. If there isn't one for what you want to do, then you might be out of luck.
 
-Additionally, you should use the [`mb_internal_encoding()`](http://php.net/manual/en/function.mb-internal-encoding.php) function at the top of every PHP script you write (or at the top of your global include script), and the [`mb_http_output()`](http://php.net/manual/en/function.mb-http-output.php) function right after it if your script is outputting to a browser. Explicitly defining the encoding of your strings in every script will save you a lot of headaches down the road.

-Finally, many PHP functions that operate on strings have an optional parameter letting you specify the character encoding. You should always explicitly indicate UTF-8 when given the option. For example, [`htmlentities()`](http://php.net/manual/en/function.htmlentities.php) has an option for character encoding, and you should always specify UTF-8 if dealing with such strings.
