Error 17734 — Title cannot contain two or more consecutive spaces or non-alphanumeric characters

Title cannot contain two or more consecutive spaces or non-alphanumeric characters.

eBay's Trading API enforces strict rules on listing titles: 80-character maximum, no HTML, no all-caps spam, no consecutive special characters or spaces, and no characters outside the printable ASCII range. Violations block the listing.

1. Trim the title to 80 characters or fewer (eBay counts every character including spaces).
2. Remove HTML tags, smart quotes, and characters outside the basic printable ASCII set.
3. Avoid keyword-stuffing patterns like multiple exclamation marks, all-caps phrases, or repeated punctuation.
4. Use natural product-language titles: brand, item name, model, key specifications, condition.
5. Resubmit through your feed or directly in the eBay Seller Hub.

• Pasting from Word or Google Docs introduces smart quotes that fail eBay's character validation
• Hidden non-breaking spaces from copy-paste — invisible but counted toward the 80-character limit
