How to fix lost line breaks when using unoconv to convert DOCX to PDF?
I used Docx template preview with Docx works well. but convert to PDF it lost line breaks.

1.Word template like this:
{{preserveLineBreaks Description}}
2.preserveLineBreaks function like this:

function escapeXml(unsafe) {
    return unsafe.replace(/[<>&'"]/g, function (c) {
        switch (c) {
            case '<': return '&lt;';
            case '>': return '&gt;';
            case '&': return '&amp;';
            case '\'': return '&apos;';
            case '"': return '&quot;';
        }
    });
}
function preserveLineBreaks(d) {  
  if(d){
    return new Handlebars.SafeString(escapeXml(d).replace(/\n/g, '<w:br/>'));
  }
}
