Keeping Special Characters Out of Problematic Evolution CMS URLs

Odd characters inside generated URLs rarely start as an Evolution CMS problem. More often they appear after external tools, ad systems, or SEO services inject their own format into links that were expected to stay clean.

The original case mentioned a broken URL pattern around an exclamation mark. That kind of issue usually appears when a third-party system rewrites, decorates, or parses the path differently than Evo expects.

What to check first

• Whether the character is really part of the Evo alias or was appended later.
• Whether a marketing, SEO, or exchange platform is altering the outgoing links.
• Whether your rewrite rules treat special characters differently from plain aliases.

Practical rule

If a site depends on stable friendly URLs, keep aliases restricted to predictable characters and normalize any incoming external variants before they hit the document parser. It is much safer to redirect strange URL variants than to teach every component to accept them.

On production Evo projects, URL discipline matters more than supporting exotic punctuation in aliases. Clean inputs and strict normalization usually save more time than permissive routing.
