Transliterator (Intl) broken in Debian Stretch

Unsupported distributions

[x] I'm not using Ubuntu Trusty (14.04)

Describe the bug A Transliterator can not be created when using the php7.0-intl version provided on packages.sury.org. The version from the Debian Stretch repository does not have this problem. The following error is encountered: transliterator_create_from_rules: unable to create ICU transliterator from rules (no parse error)

To Reproduce Run the following PHP code with php7.0-intl enabled:

<?php
ini_set('intl.use_exceptions', 1);
var_dump(Transliterator::createFromRules(':: Any-de_DE; :: Latin-ASCII;'));

Expected behavior A working Transliterator (output with version from Stretch):

object(Transliterator)#1 (1) {
  ["id"]=>
  string(13) "RulesTransPHP"
}
