Thread: IE errors loading ttf fonts -common?

    Default IE errors loading ttf fonts -common?

    Hey folks,

    doing a demo for work - in an attempt to get acceptance of the Sencha platform. One of the issues I'm running into is the @font-face error. I'm trying to host via azure websites. I've tried adding a

    <mimeMap fileExtension=".ttf" mimeType="application/octet-stream" /> entry to my staticContent section under system.webServer.

    I'm thinking this isn't an ExtJs issue per say, but figured there must be folks that have solved this in IIS or (fyi azure websites - no direct access to IIS)

    Thank you for any advice you can offer to help me solve this issue. Error below (pulled from console in IE11 windows 10)

    CSS3114: @font-face failed OpenType embedding permission check. Permission must be Installable.

    This has to do with the ttf files not being marked as embeddable. Why does Ext use ttf anyway?

    We created a workaround by loading the fonts directly from Google instead of using the ones shipped with ExtJS. This way, we're not stuck with Arial, but the errors are still there, of course

    <link href=",300,300italic,400italic,600,600italic,700,700italic,800,800italic" rel="stylesheet" type="text/css">
    As Jabe already said, you (Sencha) should really use WOFF files instead of TTF.
