-------------------------------+-------------------------------------------
 When a build script contains a wide character, rbm fails with the
 following error:
 {{{
 Error: Template Error:
 undef error - Wide character in null operation at input text line 1.
 }}}

 The reason is that in `var/build_id`, we call `sha256` on the content of
 the build script, which is using the `sha256_hex` function, which doesn't
 support wide characters:
 http://perldoc.perl.org/Digest/SHA.html#UNICODE-AND-SIDE-EFFECTS

 We currently don't use any build script with wide character in `tor-
 browser-build`. However the file `projects/tor-browser/RelativeLink/start-
 tor-browser` does contain a wide character (curly quotes: ”), which is a
 problem if we want to use it as a template (for #21998).
