> In our environment we encounter many compressed streams, one of them (which is currently not supported by Tika 1.8) is ZLIB. According to my sources and experience the magics that cover majority of ZLIB archives are these:
>     <mime-type type="application/zlib">
>         <_comment>Zlib Compressed Archive</_comment>
>         <magic priority="45">
>             <match value="\x78\x01" type="string" offset="0" />
>             <match value="\x78\x9c" type="string" offset="0" />
>             <match value="\x78\xda" type="string" offset="0" />
>         </magic>
>     </mime-type>
> Well described here:
