Re: Mac OS: invalid byte sequence for encoding "UTF8"

Hello.

When a user try to create a text search dictionary for the russian language on Mac OS then called the following error message:

  CREATE EXTENSION hunspell_ru_ru;
+ ERROR:  invalid byte sequence for encoding "UTF8": 0xd1
+ CONTEXT:  line 341 of configuration file "/Users/stas/code/postgrespro2/tmp_install/Users/stas/code/postgrespro2/install/share/tsearch_data/ru_ru.affix": "SFX Y   хаться шутся        хаться

Russian dictionary was downloaded from http://extensions.openoffice.org/en/project/slovari-dlya-russkogo-yazyka-dictionaries-russian
Affix and dictionary files was extracted from the archive and converted to UTF-8. Also a converted dictionary can be downloaded from https://github.com/select-artur/hunspell_dicts/tree/master/ru_ru

This behavior occurs on:
- Mac OS X 10.10 Yosemite and Mac OS X 10.11 El Capitan.
- latest PostgreSQL version from git and PostgreSQL 9.5 (probably also on 9.4.5).

There is also the test to reproduce this bug in the attachment.
