Special Character Codes in Guide ML

0 Conversations

If you want to put special characters into your GuideML articles, then there are two ways to do it:

  • Use a 'named entity', such as £

  • Use the <ENTITY> tag, such as <ENTITY TYPE="#163"/>

Do not use a 'numbered entity', such as &#163; - this will not work on all platforms.

We recommend the first one, as it is slightly clearer to those reading your GuideML. If you want to include special characters in article subjects, then you must use the first type of entity, as only this type will work.

The following tables show named entities and <ENTITY> tags, and contain all the characters from the ISO 8859-1 standard.

Please note that most browsers can't display all these characters (though one day one assumes they will). Some are better than others - Internet Explorer 5 displays more than Netscape 4.7, for example - so if a character doesn't appear below in your browser, then it won't show up properly for you even if you use the right code, but it might work for others. Also, some browsers will display correctly when the <ENTITY> tag is used, but not when the named entity is used. If in doubt, use the <ENTITY> tag.

Some Macintosh keyboards don't have the # symbol on them, but you can type it by pressing Option and 3.
