getBoxSize() from \Intervention\Image\Gd\Font modifies UTF-8 Text Input

[GregorVoelkl]

The getBoxSize() function of \Intervention\Image\Gd\Font has the following behaviour which seems to be unwanted.

Problem:

    $text = 'Jörg';

    $font = new \Intervention\Image\Gd\Font($text);
    $font->file(public_path('fonts/montserrat-v14-latin-700.ttf'));
    $font->valign('top');
    $box = $font->getBoxSize();

    dump($font->getText());  // internal text is: Jörg

    // getBoxSize() is called in applyToImage()
    // Jörg is written on the image
    $font->applyToImage($this->stage, 200, 200);

    dump($font->getText()); // internal text is: Jörg

Inside getBoxSize()

        $this->text = mb_encode_numericentity($this->text, array(0x0080, 0xffff, 0, 0xffff), 'UTF-8');

is called, which modifies Codepoints above 0x0080 to decimal unicode representation.

My suggestion would be either to document this behaviour or to restore the original text input.

Just found out doing this:

$text = "哈哈哈";
$font = new \Intervention\Image\Gd\Font($text);
// ...
$box = $font->getBoxSize();
$font->text($text); <--- tihs reset
// ...

solves my problem.

This issue should be resolved as of version 3.
