Word2007 Style Reader not using styleId

[begnini]

Describe the Bug

Sometimes, Word refers to his style by id, not by name. I believe this happens when the style name has accents in it.

Steps to Reproduce

Style Snippet (from styles.xml)

<w:style w:styleId="Nfaseforte" w:type="character">
        <w:name w:val="Enfase forte"/>
        <w:qFormat/>
        <w:rPr>
            <w:b/>
            <w:bCs/>
        </w:rPr>
</w:style>

paragraph snippet (from document.xml)

<w:p>
    <w:pPr>
        <w:pStyle w:val="Corpodotexto"/>
        <w:bidi w:val="0"/>
        <w:jc w:val="center"/>
        <w:rPr/>
    </w:pPr>
    <w:r>
        <w:rPr>
            <w:rStyle w:val="Nfaseforte"/>
            <w:sz w:val="28"/>
        </w:rPr>
        <w:t>Lore ipsun</w:t>
        <w:br/>
        <w:t>Lore ipsun</w:t>
    </w:r>
</w:p>
            

Expected Behavior

We expect the method PhpOffice\PhpWord\Style::getStyle($styleName) return a FontStyle when passing Nfaseforte referenced by the TextRun.

Current Behavior

Actually, Style::getStyle('Nfaseforte') is returning null (no style found) when called.

Context

Looking at the PhpOffice\PhpWord\Reader\Word2007\Styles class, in the master branch, we have the lib using the style name and, only if the name is empty, using the style id. Below the code:

https://github.com/PHPOffice/PHPWord/blob/733f845f8f93dbc4e1be5d565420aa9244626919/src/PhpWord/Reader/Word2007/Styles.php#L67:L69

I believe we should use the name and the id referencing the same style. If you are ok with this, I can create a PR.

• PHP Version: 7.2.10
• PHPWord Version: develop

[hrst]

It would be very helpful if PhpWord also reads the styleId. Using

$objReader = IOFactory::createReader('Word2007');
$phpWord = $objReader->load('filename.docx');
var_dump(Style::getStyles());

it seems that the styleId value is not read by PhpWord, and as a result cannot be used to set the style by using

$textRun->setParagraphStyle('styleId');

Any update for this would be awesome as it would allow to first read the style IDs and then use them for e.g. paragraphs.
