Font does not show up on IPad

[ralphiedee]

I know that there are certain fonts that will not display in an epub file displayed on an Ipad. I originally copied the text from an InDesign file got the font substitution msg. Once I did a test of the epub in Sigil, it looks fine in ADE but there is a font missing when viewing on IPad. I found the font, opened the container.xml file in the META-INF folder and the xml file looks like this


<?xml version="1.0" encoding="UTF-8"?>
<encryption xmlns="urnasis:names:tcpendocument:xmlns:conta iner" xmlns:enc="http://www.w3.org/2001/04/xmlenc#">
