A Javascript string like "⚡️Text" comes in, how to set the first character in the code to search for it in the string?

Answer 2

And who's stopping you from inserting the character itself? JavaScript understands Unicode perfectly.

>>> "⚡️Текст".match( "⚡" );
Array ["⚡"]

>>> "⚡️Текст".indexOf( "⚡" );
