How to print unicode characters in php?

I have a database which stores video game names with Unicode characters but I can't figure out how to properly escape these Unicode characters when printing them to an HTML response.

For instance, when I print all games with the name like Uncharted, I get this:

Uncharted: Drake's Fortuneâ„¢
Uncharted 2: Among Thievesâ„¢
Uncharted 3: Drake's Deceptionâ„¢

but it should display this:

Uncharted: Drake's Fortune™
Uncharted 2: Among Thieves™
Uncharted 3: Drake's Deception™

I ran a quick JavaScript escape function to see which Unicode character the ™ is and found that it's \u2122.

I don't have a problem fully escaping every character in the string if I can get the ™ character to display correctly. My guess is to somehow find the hex representation of each character in the string and have PHP render the Unicode characters like this:

print "™";

Please guide me through the best approach for Unicode escaping a string for being HTML friendly. I've done something similar for JavaScript a while back, but JavaScript has a built in function for escape and unescape.

I'm not aware of any PHP functions of similar functionality however. I have read about the ord function, but it just returns the ASCII character code for a given character, hence the improper display of the ™ or the ™. I would like this function to be versatile enough to apply to any string containing valid Unicode characters.

In PHP, we can use the mb_ord[] function to get the Unicode code point value of a given character. This function is supported in PHP 7 or higher versions. The mb_ord[] function complements the mc_chr[] function.

Syntax

int mb_ord[$str_string, $str_encoding]

Parameters

mb_ord[] accepts the following two parameters −

• $str_string − This parameter is used for the string.

• $str_encoding − This is the character encoding parameter. If it is absent or NULL, then we can use the internal encoding value.

Return Values

mb_ord[] returns the Unicode point value for the first character from the given string. It will return False on failure.

Example

Output

It will produce the following output −

Get the numeric value of characters
int[66]
int[100]
int[128]
int[1026]
