将SVG转换为PDF时TCPDF自定义字体问题

I've imported all my fonts to tcpdf using:

TCPDF_FONTS::addTTFfont($ttf, 'TrueTypeUnicode', '', 96);

And now i'm converting full size SVG images to pdf pages:

$pdf->ImageSVG('@' . $svg, 0, 0, $width, $height, '', '', '', 0,
false);

And i'm getting three squares at the end of all texts, how i can remove them? Bug

In the current TCPDF source code you can uncomment line 24418

$text = $this->stringTrim($text);

This did the trick for me, but I haven't tested it thoroughly and don't know why it is commented in the first place.
