Php使用preg_replace - 字符编码问题突出显示搜索词

Question

Hy guys, I need to highlight some searched words, in the result, and i was thinking to use pre_replace, and it works just fine, until i use accented characters.

So this is my code:

preg_replace("/(?<!\[)(\b{$search}\b)(?!\])/i", $replace, $string);

And if I'm looking for the word "mokus", it finds it, but leaves out "mókus",

The same thing happens the other way around.

And ideas? Thanks in advance.

You might want to research the term Accent Folding.

Here's a good article to understand the problem, the proposed solutions are in Javascript but you can translate the logic to PHP
