How to replace or escape all chinese character from a string?

I tried your code in Chrome javascript console but mine shows correctly

str = "Arc's 漢字"

$a = str.replace(/[^a-z\d\s]+/gi,'')
console.log($a) // "Arcs "

The 039s looks like it's displaying the unicode number. You don't mention where or how you are printing it.

If your looking for a regex solution in PHP, I use something like this for Japanese:

$str = "Arc's 漢字"
$new = preg_replace("/(\p{Z}|\p{P}|\p{Han}|\p{Katakana}|\p{Hiragana})+/u", '', $str )

// $this->assertEquals("Arc's", $new );

This says to replaces all

• space characters (\p{Z}),
• punctuation (\p{P}),
• Chinese characters (\p{Han}),
• Japanese hiragana (\p{Hiragana})
• Japanese katakana (\p{Katakana}) ... using unicode (/u) .. with nothing ('')

Laravel has a string->slug function that strips all punctuation and non alphanumeric characters, and lower cases the string suitable for urls

$str = "Arc's 漢字";
// $this->assertEquals('arcs', str_slug($str ));

@impbob Sorry, forgot to mention where i am going to display the output. I am sharing some text via web 'whatsapp' sharing button. When i am sharing the text to the chat, it show incorrect result. By right, everything should be worked. I have no idea and finding solution.

Not familiar with 'whatsapp'. The 039 code is for the ' (single quote) which is what is catching you up.

@impbob Yeah, i am still finding the reason why this is happening.

The problem occurred if retrieve the data from my database, and it will show apostrophe as ' . Anyone know how to solve this?
