In PHP, getting the character corresponding to a specified Unicode code point is a common task. Unicode is a character encoding standard for representing text across different platforms and languages.

Question: How to get the character of U 010F?

For example, how to get the character corresponding to the U 010F Unicode code point? This code point corresponds to the Latin lowercase letter o with an acute accent, or "ó".

Answer:

PHP provides several functions to handle Unicode encoding points:

• hexdec() :Convert a hexadecimal string to a decimal integer.
• mb_ord(): Get the Unicode code point of the string (multi-byte string support).
• mb_chr(): Convert Unicode code points to strings (multi-byte string support).

Here is the sample code to get the U 010F character:

<code class="php">var_dump(hexdec('010F'));

var_dump(mb_ord('ó')); // 243
var_dump(mb_chr(243)); // ó</code>
