Side note:  These are part of the extended ASCII character set.  It includes language-specific characters and line drawing characters.  On some older systems these are considered unprintable.

 Historically, HTTP has allowed field content with text in the ISO-8859-1 charset [ISO-8859-1], supporting other charsets only through use of [RFC2047] encoding.  In practice, most HTTP Header field values use only a subset of the US-ASCII charset [USASCII]. Newly defined header fields SHOULD limit their field values to US-ASCII octets.  A recipient SHOULD treat other octets in field content (obs-text) as opaque data.
