* test-suite/lib.scm (with-locale, with-locale*): new test functions * test-suite/tests/encoding-escapes: don't fail if en_US.utf8 doesn't exist * test-suite/tests/encoding-iso88591.test: set and restore locale, if possible * test-suite/tests/encoding-iso88597.test: set and restore locale, if possible * test-suite/tests/encoding-utf8.test: set and restore locale, if possible * test-suite/tests/srfi-14.test: don't need to setlocale to Latin-1 to test Latin-1 since string conversion is handled at read/compile time. Set and restore locale, if possible.
