When export a report to PDF change the font

I'm using Jaspersoft Studio 5.2, and I did a report with Courier New font, and when I exports this to PDF, it's change the font to Arial.

I'm using just the Studio tool. When I preview the report is all right, but when I export it's happens.

What can I do with my report to export with Courier New font?

My textField model that I'm using in report:

<textField pattern="dd/MM/yyyy  HH:mm:ss">
    <reportElement uuid="f50b279a-b480-498f-8af7-be7e23c4b80b" x="415" y="11" width="105" height="10"/>
    <textElement>
        <font fontName="Courier New" size="8"/>
    </textElement>
    <textFieldExpression><![CDATA[new java.util.Date()]]></textFieldExpression>
</textField>

You should use the Font Extensions mechanism.
