^[a-zA-Z0-9.\\-_'!()áéíóúÁÉÍÓÚüÜñÑÀàÂâÆæÇçÈèÉéÊêËë
ÎîÏïÔôŒœÙùÛûÜüŸÿ«»€,&\\/~"`@#$%*=+\\[\\]:;?©®\\^|\\\\ 
]{1,300}$
3. ESAPI is not recognizing €, Œ,œ, Ÿ characters.

What is the expected output? What do you see instead?

Instead it is treating them as invalid. When i printed the regex which is

Facing the exact same issue, except on the encoding side.

When a string containing the french characters (€, Œ,œ, Ÿ) is entered it 
replaces them for other safe characters.

Thanks.
