Biber error on Mac - locale and bibtex subsystem issues

Question

Biber runs with this warning:

Running `Biber' on `citation_issues' with ``biber citation_issues''
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LC_ALL = (unset),
    LANG = "en_TW.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

And this error:

WARN - BibTeX subsystem: /var/folders/rw/rpr418x91h13ysbc6k7fzj240000gn/T/XreBNpegVI/thesis.bib_98780.utf8, line 7325, warning: "(" in strange place -- should get a syntax error

INFO - WARNINGS: 1

Locale settings on the terminal do not concur with what biber reported.

$ locale
LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL="en_US.UTF-8"

How do we resolve that?

The error above was apparently caused by this .bib entry.
