The accented letters can also be obtained by spelling them out, for example:

&eacute; is the same as &#233; - i.e. é (an 'e' with an acute accent)
&Agrave; is the same as &#192; - i.e. À (an 'A' with a grave accent)
The accents are:

• acute
• circ (circumflex accent)
• grave
• tilde
• ring
• slash
• uml (dieresis or umlaut)
• cedil (cedilla)

Note: not all letters have all the accents.

Many of the other symbols can be called via name as well, for example:

&AElig; - Æ - Capital AE dipthong (ligature)
&ETH; - Ð - Capital Eth (Icelandic)
&THORN; - Þ - Capital THORN (Icelandic)
&szlig; - ß - Small sharp s, (German, sz ligature)
