如何修复模式描述中的“字符串中的错误转义序列”

Question

I have use GTM to tag the schema variables.

<script type="application/ld+json">
{
  "@context": "http://schema.org",
  "@type": "Product",
  "name": "{{Product-name}}",
  "description": "{{Product-description}}",
  "category": "{{Product-category}}",
  "image": "{{Product-image}}",
  "sku": "{{Product-reference}}",
  "offers": {
    "@type": "Offer",
    "url": "{{Page Path}}",
    "Price": "{{Product-price-with-dot}}",
    "priceCurrency": "[EUR]",
    "itemCondition": "https://schema.org/NewCondition",
    "availability": "{{Product-stock}}",
    "seller": {
      "@type": "Corporation",
      "name": "Magic4media"
    }
 }
}
</script>

All seems OK except for the variable value "Description" of some products whose description contains special characters. The original text is converted with more and more special caracteres... and return "Bad escape sequence in string".

Product-description variable set up

Original text description:

id="pPdtDesc">Sac  shopping en coton avec anses longues. 140 gr/m². Produit sous une norme certifiée pour l'utilisation de substances nocives dans le textile.

Product description with "Bad escape sequence in string" result

How can I fix all any possible problems with special characters?

The answers was:

 function(){ var string = {{Product-description}}; return string.replace(/[^a-zA-Z0-9]/g, ''); }
