HTML 4.01 Entities Reference

HTML 4.01 supports the ISO 8859-1 (Latin-1) character set.

The lower part of ISO-8859-1 (codes from 0-127) is the
original 7-BIT ASCII
standard.

Most of these characters can be used without a character reference.

The higher part of ISO-8859-1 (codes from 160-255) can all be used using
character entity names.
