Add enc Parameter to addTTFFont

[aadlung]

Depending on the fonts, using special characters (e.g. in Germany or Hungary) sometimes require to add a font with a utf-8 encoding (not on the document, but on the font), even if the file is of the type "TrueType".

The DocumentViewHelper.php file uses the following syntax:

$fontName = \TCPDF_FONTS::addTTFfont($path, $type, '', 32, $outputPath);

So the encoding of the font file is always empty.

Describe the solution you'd like
I would ask to replace it with the following two lines, to enable adding "utf-8" as setting in typoscript:

$enc = isset($ttfFont['enc']) ? $ttfFont['enc'] : '';
$fontName = \TCPDF_FONTS::addTTFfont($path, $type, '', 32, $outputPath);

@aadlung Thanks for creating this issue! We will sure add this as a parameter, I will also check whether it makes sense to add the remaining parameters as well.

@aadlung I added this parameter in v2.3.2 which I just released.
