Unicode character in PHP string

Question

This question looks embarrassingly simple, but I haven\'t been able to find an answer.

What is the PHP equivalent to the following C# line of code?

s         


        

Answer 1

Because JSON directly supports the \uxxxx syntax the first thing that comes into my mind is:

$unicodeChar = '\u1000';
echo json_decode('"'.$unicodeChar.'"');

Another option would be to use mb_convert_encoding()

echo mb_convert_encoding('က', 'UTF-8', 'HTML-ENTITIES');

or make use of the direct mapping between UTF-16BE (big endian) and the Unicode codepoint:

echo mb_convert_encoding("\x10\x00", 'UTF-8', 'UTF-16BE');

Answer 2

Try Portable UTF-8:

$str = utf8_chr( 0x1000 );
$str = utf8_chr( '\u1000' );
$str = utf8_chr( 4096 );

All work exactly the same way. You can get the codepoint of a character with utf8_ord(). Read more about Portable UTF-8.
