Web typography is evolving.
Today there is a thing called Web Fonts, which essentially are typefaces that do not need to be installed in the computer of the person who is browsing the given web page. Possibly a new version of a browser, which changes its @font-face support? The support status for widely used brosers can be viewed at caniuse.com.

A tool for creating a custom font from SVG files, fontcustom uses the following collection of rules:
@font-face {
font-family: "fontcustom";
src: url("fontcustom.eot");
src: url("fontcustom.eot?#iefix") format("embedded-opentype"),
url("fontcustom.woff") format("woff"),
url("fontcustom.ttf") format("truetype"),
url("fontcustom.svg#fontcustom") format("svg");
font-weight: normal;
font-style: normal;
}
@media screen and (-webkit-min-device-pixel-ratio:0) {
@font-face {
font-family: "fontcustom";
src: url("fontcustom.svg#fontcustom") format("svg");
}
}
The different font file formats are supported by different (desktop) browser vendors:
The SVG version is essentially needed for mobile browsers, namely Webkit-based.
Thus, simply using src: url("fontcustom.woff") format("woff"); should make the font available in all recent/modern desktop browsers.
