CMS 12 - API V3 - Invalid non-ASCII or control character in header: 0x2212

Reposting this in correct room and description

Invalid non-ASCII or control character in header: 0x2212"

If you have multi-culture enabled and query delivery api in 'nb-no' culture whereas no issues for any other culture so far - but possibly could happen for other cultures i've only tried from a list of few

/api/episerver/v3.0/content/?contenturl=/nb-no/page-url/&expand=*

I started investigating this bit by bit and in the end it turns out the problem was coming from [OutputCacheFilterAttribute] when it tries to add etag hash-code (ETag hash contains non-ascii characters) in header like

 typedHeaders.ETag = new EntityTagHeaderValue((StringSegment)("\"" + evaluateResult.ETag + "\""));

These are all private/seal classes methods so nothing much you can do to control it - any chance it can be base64 encoded before adding to header as .net 5 as of now does not seem to support non-ascii characters in header

Or any chance api can provide some options to control/disable etag generation? There is a ContentETagGenerator available but OutputCacheFilterAttribute re-generate hash again within its private methods.

Many thanks,

Kashif

Are you using the released version of Content Delivery? This a known bug that should've been fixed.
