IE8 bootstrap3 glyphicons icon does not display the problem

Today to do the project, found in the IE8 under the bootstrap in the Glyphicons icon does not display, a large number of access to information, also did not find the reason, later after careful investigation found a problem, as follows:

The correct wording should be

Src:url (".. /fonts/glyphicons-halflings-regular.eot? #iefix ") format (' Embedded-opentype '),

Changed to a question mark after the use, if still do not show, the whole paragraph mentioned @font-face page, put in

The confusion that has been caused to me at the moment is whether there is a bug in the version before bootstrap3.3, resulting in the eot-#iefix.

I see the bootstrap3.3 version is the correct wording for EOT? #iefix.
