"®" symbol in pkg-config file breaking downstream build tools

[elldritch]

Hi there! I've been digging into haskell/cabal#9608, which is caused by being unable to parse output from pkg-config --list-all when libvpl is installed.

This is because a "®" symbol was added to the Name and Description properties of vpl.pc when this project was renamed from "oneVPL" to "libvpl". See the file https://github.com/intel/libvpl/blob/master/libvpl/pkgconfig/vpl.pc.in in commit 44df6e0.

This results in an invalid pkg-config file. Note that the pkg-config manpages (link) define:

Properties are set using RFC822-style stanzas which consist of a keyword, followed by a colon (:) and then the value the property should be set to.

And RFC-822 defines property field bodies to be ASCII characters only, and "®" is not an ASCII character.

Can you please remove this ISO/IEC 8859-1 symbol from the .pc output files? Thanks!

@elldritch Thanks for the report! We will make sure is fixed in the next release!

@mav-intel Thank you! When do you expect the next release to be? This is breaking my builds today, so I am figuring out whether to work around it by temporarily downgrading or whether to temporarily patch it myself.
