.ttf – All browsers which are compatible to CSS3.
All the font types may be having same name.
@font-face
For example: Brandon.ttf, Brandon.otf, Brandon.eot. If we upload all the types in same folder as like the below screenshot and when we request for ‘eot’ extension, it may download any of the font-type or same. Mostly it will download the first item in the folder. This is not consistent.
When I tested with the below url, http://sample/~/media/css/fonts/brandon.eot,
it downloaded woff font type.
So ideally the above CSS should be able to download the font depending upon the extension and the browsers.
Few hacks and ideas:
1. Rename the font file name for each type, upload it in Media library and use it
in CSS src attribute. Then the requested url should be able to download the font as we will be having one font in each type.
Also add the following mime type for the font.

Mime

.ttf
|
font/truetype

.otf

font/opentype

.eot

application/x-font-woff

2. In IE9, you may get error “@font-face failed OpenType embedding permission check.
Permission must be Installable.” Fix: “Obtain the correct permission or licenses for embedding the font.” – Source: http://blog.beacontechnologies.com/custom-fonts-i-internet-explorer/
<!-- MEDIA - REQUEST EXTENSION
The extension to use in media request URLs. If the value is not set, the Extension field of the individual media items will be used (ie. JPG, GIF, etc.)
Default value: "ashx"-->
Go to Web.config file and find a setting named “ItemNameValidation” and change the validation to allow dots.
Modified Regular Expression.
In Sitecore, if the current context user doesn’t have permission to access this item, Sitecore will return null or throw exception.
SecurityDisabler:
SecurityDisabler will elevate the context user to have administrative privilege and so context user will be able to do anything on the system.
new Sitecore.SecurityModel.SecurityDisabler();UserSwitcher:
UserSwitcher allows a segment of code to run under a specific user instead of current context user.
new Sitecore.Security.Accounts.UserSwitcher(Sitecore.Security.Accounts.User.FromName("username",false));Note: It is recommended to provide context user with appropriate rights than using SecurityDisabler or UserSwitcher.
Sample Code:
/// <summary>
/// Code snippets explaining SecurityDisabler and UserSwitcher
/// </summary>
private void SecuritySample()
{
//Getting Master Database
Sitecore.Data.Database masterDB = Sitecore.Configuration.Factory.GetDatabase("master");
//Getting a Sitecore Item
Sitecore.Data.Items.Item home = masterDB.GetItem("/sitecore/content/Home");
//Using Begin, End, Cancel Edit and Security Disabler
BeginEditAndSecurityDisabler(home);
//Using EditContext and Security User Switcher
EditContextAndSecurityUserSwitcher(home);
}
/// <summary>
/// Using Begin, End, Cancel Edit and Security Disabler
/// </summary>
/// <param name="home"></param>
private void BeginEditAndSecurityDisabler(Sitecore.Data.Items.Item home)
{
using (new Sitecore.SecurityModel.SecurityDisabler())
{
home.Editing.BeginEdit();
try
{
home["Title"] = "Title from Code";
//Commit the changes
home.Editing.EndEdit();
}
catch (Exception)
{
//Revert the Changes
home.Editing.CancelEdit();
}
}
}
/// <summary>
/// Using EditContext and Security User Switcher
/// </summary>
/// <param name="home"></param>
private void EditContextAndSecurityUserSwitcher(Sitecore.Data.Items.Item home)
{
//User which is already created in Sitecore User Manager
string testUser = @"sitecore\testuser";
//User existing or not
if (Sitecore.Security.Accounts.User.Exists(testUser))
{
//Getting Sitecore User Object with UserName
Sitecore.Security.Accounts.User scUser = Sitecore.Security.Accounts.User.FromName(testUser, false);
//Switching Context User
using (new Sitecore.Security.Accounts.UserSwitcher(scUser))
{
//Using EditContext to edit an Item
using (new Sitecore.Data.Items.EditContext(home))
{
home["Text"] = "Modified Text from Code";
}
}
}
}
