Hello ,

The EPUB3 specification now mandates WOFF 
http://idpf.org/epub/30/spec/epub30-contentdocs.html#sec-css-fonts


=========== start quote ===============
3.3.4 CSS Fonts Level 3

EPUB Style Sheets may include @font-face rules as defined in the CSS Fonts Module Level 3 [CSS3Fonts] specification. OpenType [OpenType], WOFF [WOFF] and SVG [SVG] fonts may be referenced using @font-face rules.

Reading Systems with a CSS Viewport must support OpenType [OpenType] and WOFF [WOFF] fonts embedded using the @font-face rule, as well as the font obfuscation mechanism defined in Font Obfuscation [OCF3] . Reading Systems may support SVG fonts.

In addition, Reading Systems must support at least the following @font-face font descriptors:

    font-family

    font-style

    font-weight

    src

    unicode-range

Refer to Intrinsic fallback: CSS Embedded Fonts [Publications30] for font fallback processing requirements.
