How is an EOT font created?
EOT fonts can be created using Microsoft’s Web Embedding Fonts Tool (WEFT), or various other free utilities. WEFT can be obtained here. The utility modifies a TrueType® or OpenType (TrueType flavored only) font supplied by the user to create the EOT file. The user enters the Web domain that will be linked to the EOT file. WEFT also allows the user to “subset” the font during the process. This removes characters from the font that are not used by the Web page, thereby reducing the file size of the font.
