Bad conversion in this case

RTF Translation is wrong in this case:

`<?php
error_reporting(-1);
ini_set('display_errors', 'on');
require DIR . '/vendor/autoload.php';

use RtfHtmlPhp\Document;
use RtfHtmlPhp\Html\HtmlFormatter;

$original = "{\rtf1\ansi\ansicpg1252\deff0{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}}\viewkind4\uc1\pard\lang1036\f0\fs16 m'e9lange ma'efs fran'e7ais\par}";
$document = new Document($original); // or use a string directly
$formatter = new HtmlFormatter('UTF-8');
$r = $formatter->Format($document);
file_put_contents('rtf.html', $r);
echo $r;
?>`

Result:

tf1onttbl0nilcharset0 Microsoft Sans Serif;iewkind40s16 mélange maïs français

Expected result:
Something like "Mélange maïs français"

Thanks,

Start with the supplied PHP reproduction, tracing Document and HtmlFormatter as the RTF is parsed and formatted. The fix is done when the example produces the expected “Mélange maïs français” text without RTF control-word artifacts; no test file is named in the issue.
