The new functionality we got in 3.4.2 as part of CRM-7981 which allows custom mailing label format creation from within the UI is great, but introduces one regression:
National characters (e.g. the Czech ě č ř) are not printed properly since the currently available fonts (Helvetica, Times and Courier) don't support these special characters.
Luckily TCPDF contains the Deja Vu Sans font that is capable of printing these, it just wasn't enabled as part of the recent rewrite.

To fix:
in CRM\Utils\PDF\Label.pdf at line 189 insert
            'dejavusans' => ts('Deja Vu Sans (UTF-8)'),
This registers the dejavusans font provided with TCPDF to be available for mailing labels usage.

When porting your custom mailing label from code into the new manager, just select Deja Vu Sans as the label's font if special characters are needed. If you're using the baked in labels you need to update the font in them as well.
