Send HTTP request - Invalid character in header content

Hi, it seems like you have a bug on the “Send HTTP request”.
I am from israel so we write in hebrew and it seems like your system can’t recognize hebrew characters.

So if i use a word like “שלום”, you system won’t allow me to send the data.

So that mean this option at the moment is not supporting other lanagues that are not english:

Update: It seems like i usesd headers instead of query so i still testing it out again.
