Extended Character Set


My favorite: to get space is and sign followed by nbsp; 
This is a table for my personal use. Most of the extended characters for HTML are for foreign languages. A few may be useful. The way to get them is shown in this example:

 You use the ampersand & and number sign # followed by a number from this table. If the number is 181, you get a Greek mu (the only Greek letter in this set).

Left bracket is a problem because it signals a HTML command. Use ampersandlt; to get <

One way to get symbols for valances of ions is to use commands for subscripts and superscripts:
