Could you share a minimal playground example where it's failing?

My template have a custom break line fuction. template like this:
{{preserveLineBreaks foo}}

the function as below:

function preserveLineBreaks(d) {
    return new Handlebars.SafeString(d.replace(/\n/g, '<w:br/>'))
}

please see the example here:

Handlebars by default escape XML, but when you use Handlebars.SafeString you explicitly say you don't want that.
The solution would be to explicitly escape the input parameter.

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) {
    return new Handlebars.SafeString(escapeXml(d).replace(/\n/g, '<w:br/>'))
}
