Don't set locale explicitly. musl supports UTF-8 by default.
With this change pdfgrep fails with:
terminate called after throwing an instance of 'std::runtime_error'
what(): locale::facet::_S_create_c_locale name not valid
Aborted
Unless LANG is set explicitly.
Alternative solutions:
* Use the "C" lang instead of the "" lang?
* Catch the error and ignore it?
