Like it or not, our Internet was created to be English-language focused. As the Internet and Web were being developed there was only one core character set: ASCII. Most of the RFCs defined a character set that was based around ASCII [here], and which only support a limited number of characters. With Unicode [here] we have 16 bits to represent characters, and can then represent almost every character we need.
