Re: [exim] Filter with special characters (!?)

Hello, I need to use the following symbols exclamation mark and question mark (! ?) as characters in a filter but using HEX does not work.

discard    condition = ${if match{$header_subject:}{^\277Eres el del video?\$}}
logwrite = Rejected By SPAM - $header_subject - FROM: "$sender_address"

I understand that using the standard ISO-8859-1 should be work, but no.

\277 is equal to ==> !

but it does not detect it as a character inside the filter

Regards,
