Why do Google Ads reject copy with em dashes?

Google Ads editorial policy requires standard ASCII punctuation in ad headlines and descriptions. Em dashes (U+2014) are non-ASCII Unicode characters and will cause the ad to be disapproved.

Can we integrate this into our content workflow?

The tool is browser-based for immediate use. For automated pipeline integration, the same cleaning logic can be implemented as a pre-publish script using the same Unicode replacement rules.

Does this work for localized copy?

Yes. The tool handles all Unicode scripts. Typographic artifacts in localized AI copy — including non-Latin scripts — are detected and cleaned correctly.

Will cleaning change the character count for ad platforms?

Yes — it will make the count accurate. Hidden zero-width characters inflate counts invisibly. After cleaning, the character count matches what ad platforms actually count.

Is campaign copy uploaded to any server?

No. All processing is browser-local. Confidential copy, pricing, and campaign details are never transmitted anywhere.

Marketing teams using AI copy tools at scale face a systemic encoding problem: every AI-generated asset carries hidden Unicode characters that corrupt email HTML, break ad platform character limits, cause rendering failures in CMS templates, and inflate word counts in localization tools. This tool cleans every asset before it enters your delivery pipeline.

AI artifacts that break marketing pipelines

These encoding issues appear in AI-generated copy and cause downstream failures in ESP, CMS, ad, and localization tools.

Non-breaking spaces in email HTML

AI copy pasted into email HTML templates introduces   entities that break responsive layouts, inflate preview text length, and trigger spam filters in some ESPs.

Em dashes in ad copy

Ad platforms — Google Ads, Meta, LinkedIn — have strict ASCII character requirements. Em dashes submitted in headlines are rejected or silently truncated, wasting budget on disapproved ads.

Zero-width characters in CMS fields

Zero-width spaces inflate character counts in CMS slug generators, meta description fields, and localization memory tools, causing validation errors and false-positive duplicate content flags.

Curly quotes in template variables

Marketing templates use shortcodes and variable syntax with straight quotes. AI-generated curly quotes silently break variable substitution, causing raw code to appear in sent campaigns.
