RegEx for Mathematical Alphanumeric Symbols

I have been trying to remove bold characters like this:

 - New song

As you see is a bold text without <b> tag.

I had tried this, assuming that the characters are probably a type of emoticon, but I have not had any luck.

$regex_emoticons = '/[\x{1F600}-\x{1F64F}]/u';
$clear_string = preg_replace($regex_emoticons, '', $string);

$regex_symbols = '/[\x{1F300}-\x{1F5FF}]/u';
$clear_string = preg_replace($regex_symbols, '', $clear_string);

$regex_transport = '/[\x{1F680}-\x{1F6FF}]/u';
$clear_string = preg_replace($regex_transport, '', $clear_string);

$regex_misc = '/[\x{2600}-\x{26FF}]/u';
$clear_string = preg_replace($regex_misc, '', $clear_string);

$regex_dingbats = '/[\x{2700}-\x{27BF}]/u';
$clear_string = preg_replace($regex_dingbats, '', $clear_string);

How can I remove it or replace for correct char without bold? Any idea it will be apreciated.

These characters belong to the Unicode Mathematical code block

\p{Block=Mathematical_Alphanumeric_Symbols} which covers the range [\x{1D400}-\x{1D7FF}]

These characters are a mix of font looking codes like bold, italic-bold, script, script-italic, script-italic-bold.

They could be mapped to ASCII equivalent if you want to take the time to match each type and range.

I would just delete them.

Here are the characters in the block range ( heavily abbreviated )

Initially, I thought this would be an uppercase/lowercase problem. You can likely follow the same with proper unicodes that you might want to find out.

One problem with your expressions might be that + might be missing.

My guess is that maybe this expression might work:

([\x{0041}-\x{005A}]+)

if everything might be uppercase, or maybe some expressions similar to:

([\x{0041}-\x{005A}]{2,})

if we just want to replace SONYA and not S O N Y A.

In this demo, the expression is explained, if you might be interested.

Test

$re = '/([\x{0041}-\x{005A}]+)/u';
$str = 'SONYA';
$subst = '\\L$1';

$result = preg_replace($re, $subst, $str);
echo $result;

Reference

unicode of lower case and upper case letters
