Subject: Re: DOCBOOK-APPS: representing and rendering symbol characters
/ Bob Stayton <bobs@sco.COM> was heard to say: | The entity renders properly in IE 5.5, but appears as a "?" in | Netscape 4.75 on Windows and Netscape 4.76 on Linux. | I didn't try a Mac. It doesn't surprise me that these don't render properly on all platforms with all browsers. For one thing, the browser needs access to a font that includes the symbol. | Jirka, are you sure you saw these entities rendered properly | in "mozilla for Windows" (was that Netscape 4.7)? Even Mozilla on Linux gets it right. They must have added a Unicode font. | Were you perhaps thinking | that Netscape supports the utf-8 character set? If | you render your output as utf-8 and add this: | | <META HTTP-EQUIV="Content-Type" CONTENT="text/html;charset=utf-8"> This whole issue is so murky... UTF-8 is a scheme for encoding a sequence of characters into a sequence of octets. UTF-8 has nothing to do with whether or not ∞ is rendered. In UTF-8, the character at Unicode position 8734 could be represented as a sequence of three (or possibly four, I don't recall the precise algorithm) octets. But after parsing the document, that sequence and the sequence ∞ have the same meaning: they represent Unicode character 8734 which is the infinity symbol. | The HTML 4.0 spec has been around since 1997, so why haven't | these standard character entities been implemented in Netscape? HTML 4.0 explicitly calls out[1] the fact that not all user agents may be able to display all characters. | So I think Erik's original question still stands: how do you render | the symbol font characters universally on all HTML browsers? You can't. | It looks like image files are the only universal form. They aren't. Lynx and wn can't display graphics. Be seeing you, norm [1] http://www.w3.org/TR/1998/REC-html40-19980424/charset.html#h-5.4 -- Norman Walsh <ndw@nwalsh.com> | Why shouldn't things be largely http://www.oasis-open.org/docbook/ | absurd, futile, and transitory? Chair, DocBook Technical Committee | They are so, and we are so, and | they and we go very well | together.--Santayana
