I have no strong objection for UTF8-encoded files (stop words or ispell or
synonym or thesaurus). Just recode it after reading.
But configuration for different languages might be differ, for example russian
(and any cyrillic-based) configuration is differ from west-european
configuration based on different character sets. So, we should have non-obvious
rules for stemmers to define which exact stemmer and stop-file should be used.
For russian language with utf8 encoding it should use for lword english stemmer,
but for italian language - italian stemmer. Any ASCII chars can't present in
russian word, but might italian word can contains only ASCII.
