<META http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
in which "charset" names are from the IANA / MIME registry.
If the characters do not display correctly in your browser, it means your browser does not understand the declaration, or it does not support that character set, or you don't have an appropriate font. However, you can still save the file and use it locally.
If you save a table, you can use it (you might want to keep only the part between <pre> and </pre>) to test character-set aware software. For example, if you save it on a host, then make a terminal connection (ssh, telnet, dialup, whatever) from your desktop computer to the host, you can see if your character-set definitions are working, and/or if you are using an appropriate font.
Note that nonprintable characters such as Soft Hyphen are likely to occupy no space in the display. Even though the brackets appear to be empty, there really is a character between them.
Just a few tables to begin with. If you need one that's not here, let me know and I'll add it.

You can find plain-text (not embedded in HTML) versions of these tables (and many more) in the Kermit FTP archive: ftp://kermit.columbia.edu/kermit/charsets/; transfer them in BINARY mode only. For any pair of files xxx.c and xxx.txt, the first is a C program to generate the table, the second is the table itself.
