JRS appends locale to inline font-family CSS declaration

Issue Description

We have added a fonts.jar file to WEB-INF/lib so that our Tahoma font specified in reports will be embedded in the PDF export. As a result, JRS now appends the locale to the font family and this results in the viewer not rendering Tahoma. For example, the inline CSS font-family now is Tahoma Bold-Bold-en_US_Mtrad. How can we stop JRS from appending the locale to the font-family? We would like Tahoma to be rendered in the viewer and in the exports. Right now it is not possible to do that.

Resolution

Add the following to WEB-INF/classes/jasperreports.properties:

net.sf.jasperreports.web.resource.pattern.fonts=fonts/.*

On IE, you might get this error.

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

be Installable.

IE expects TTF fonts to have the embeddable flag set to Installable, and

refuses to use the fonts otherwise.

The solution is to use a font tool to either change the embeddable flag in the

TTF file, or to convert the file to EOT and add the EOT file to the extension

along the TTF file. Of course, you will need to check whether you have

permission to update or convert the TTF file...
