Font in heading 1, 2 and 3

In the article I write: "Isolamentos térmicos"
I put it in heading 1 or heading 2 and the display in the backoffice the display is "Isolamentos térmicos" (bigger text and bold) and in the frontoffice the display is "ISOLAMENTOS TRMICOS" - text is in capitals, with shade and the character "é" is missing.
I tryed to change font and shadding in layout.css and template_cs.css but it doesn't work with Headings and article and category titles.

Please read this post: www.hotjoomlatemplates.com/support-forum...e-characters-in-sifr

Is it possible to change the font of sIRF? Because most of users will not have the correct font and the display will be not correct.

How you mean the display will be not correct? Even users without this font installed on system will see the font. That's purpose of sIRF. You can disable it if you like in template parameters.

Ok! I understand now the purpose of sIRF, but as portuguese characters are not there, the solution is to disable it. Thanks.

You can enable all characters, just replace fonts file in template, as it's described on link that I sent.
