unsupported charset in HTTP response

Description

I got error "Lucee 5.3.9.166 Error (java.nio.charset.UnsupportedCharsetException) Message: binary" when I try to call endpoint with header "Content-Type: application/pdf;charset=binary"

I reproduced this bug:

enpoint.cfm:
<cfcontent reset="true">
<cfcontent file="c:\17797.pdf" type="application/pdf; charset=binary">

caller.cfm
<cfhttp method="GET" url="...enpoint.cfm">
</cfhttp>

throws

lucee.runtime.exp.NativeException: binary   at java.base/java.nio.charset.Charset.forName(Charset.java:529)   at lucee.commons.io.CharsetUtil.toCharset(CharsetUtil.java:53)   at lucee.runtime.tag.Http._doEndTag(Http.java:1144)   at lucee.runtime.tag.Http.doEndTag(Http.java:697)`

I've checked this ticket with all the fixed version builds. Now the response with the header "Content-Type: application/pdf;charset=binary" works fine for the binary content.

problem is that “binary” is not a charset at all

Fixed
