The fonts and icons should be located under the content\kendo\{your kendo version}\
(assuming you are creating an MVC.net site based on the tag (see image below)
if this is missing then try running the upgrade wizard in visual studio (assuming you are using visual studio here) or just include the files you require from your distribution.
can you also check you have included the required css links within your site (please note I am using the bootstrap theme here so alter to work with your theme as required):
<link href="@Url.Content("~/Content/kendo/2017.1.118/kendo.common-bootstrap.min.css")" rel="stylesheet" type="text/css" />
<link href="@Url.Content("~/Content/kendo/2017.1.118/kendo.mobile.all.min.css")" rel="stylesheet" type="text/css" />
<link href="@Url.Content("~/Content/kendo/2017.1.118/kendo.dataviz.min.css")" rel="stylesheet" type="text/css" />
<link href="@Url.Content("~/Content/kendo/2017.1.118/kendo.bootstrap.min.css")" rel="stylesheet" type="text/css" />
<link href="@Url.Content("~/Content/kendo/2017.1.118/kendo.dataviz.bootstrap.min.css")" rel="stylesheet" type="text/css" />
if this is set up correctly just make sure the fonts etc are set to "content" for the 'Build Action'
