[debhelper-devel] Bug#815620: addsubstvar fails if there are utf characters in the substvar file

[Joachim Breitner]

Package: debhelper
Version: 9.20160115
Severity: important

Hi,

A few (Haskell) packages fail to build because addsubstvar in Dh_Lib.pm,
which uses grep, falls over unicode characters in existing substvar
lines. It makes lines like
Binary file debian/libghc-gitit-doc.substvars matches
appear in the substvar file, which obviously breaks.

The fix is simple: In Dh_Lib.pm, replace calls to "grep -s -v" with
"grep -a -s -v".

Greetings,
Joachim
