There was a conversation about this on x3d-public a few years back... We committed to adding it in X3D 4.1 and (if I recall correctly) also noted that adding a url field might enable usage of larger font files.</div>

A goal for X3D 4.1 is use of font files in FontStyle (see Mantis <span style="color: rgb(51, 122, 183);">
<a href="https://mantis.web3d.org/view.php?id=1464" id="OWA289b6344-d969-82e2-63b1-2aae697fc317" class="OWAAutoLink" title="[assigned] candidate features for X3D 4.1" style="color: rgb(51, 122, 183);">0001464</a></span>).<br>
<br>
Addition of individual-font files might be accomplished by listing the font file name in the FontStyle 'family' field.<br>
<br>
Referencing different fonts in a single combined font library file may require an additional field, for example 'url'. In general the use of a font library may be preferred, but repeatedly run-time retrieval of a font library is not desirable, since the file
might be quite large and rarely changing. This might be noted in the specification prose, e.g.<br>
<br>
- "MFString [in,out] url [] [URI]"<br>
- "The family field may list a specific font file. A font listed in the family field may be provided by a corresponding font library."<br>
- "The url field may refer to a font library. Font libraries can be used by multiple FontStyle nodes in a scene and need only be loaded once per session."<br>
<br>
Support levels: add "Level 2, FontStyle, support for font files in family field and support for font libraries via url field ."<br>
<br>
Security, licensing, and copyright/usage issues are handled via the exposure of the font file itself. If retrievable (locally or online) then proper access is presumably handled separately.</div>
