doesn't know about the entity name "divide" and just puts it
literally.
This table grew out of an overview of the "ISO
Latin-1 Character Set" overview related to the Hyper-G Text Format
(HTF).
The entity names &brkbar; and Đ
seem to be unique to HTF.
The entity name &hibar; has been supported by X Mosaic
but seems to be replaced with ¯.
The entity names ¨ and ¨ should
be equivalent.
The standards stuff:
The 
HTML 2.0 Standard
includes a section on
Character Entity Sets
and an overview on the
HTML Coded Character Set
(The entity names are derived from ISO 8879).
Or have a look at the
Latin-1 Character Entities
as listed in an draft for the
HTML 3.0 specification.
The
Appendix II
of CERN's
HTML+ Discussion Document
contains a
table
(in PostScript format) of the proposed character entities for HTML+ and their
corresponding character codes for Unicode and the Adobe Latin-1 & Symbol
character sets.
Please note that there is nothing wrong with using characters of ISO Latin-1 above 127: the normal transmission protocol for the WWW, HTTP/1.0, uses the 8bit ISO latin-1 as default encoding. (Thanks to Roman Czyborra for pointing this out!)
