Disallowed Symbols or Special Characters

Your product title, description, or keyword contains symbols or special characters Microsoft does not permit, such as @, %, #, or unicode decorations used outside their valid context.

Trademark/copyright symbols, registered marks, currency symbols mid-text, or ASCII art used as visual separators. Also caused by encoding errors that introduce mojibake (e.g., — in place of em-dash) and HTML entities not decoded.

1. Strip non-alphanumeric characters except basic punctuation (, . ' -)
2. Decode HTML entities like & before submission
3. Convert smart quotes and em-dashes to ASCII equivalents
4. Test feed in UTF-8 encoding only

• Trademark ™ in brand names is usually allowed but may fail
• Encoding from Excel exports mangles characters
