charset_table is not a path directive, it declares how characters are (or not) indexed, for example:
charset_table = 0..9, A..Z->a..z, _, a..z, \
U+410..U+42F->U+430..U+44F, U+430..U+44F, U+401->U+451, U+451
Means numbers, latin, _ and russian characters are indexed (anything else is replaced with a whitespace). Also uppercases are mapped to lowercases (Apple and apple will match the same).
You can use the newly non_cjk alias, it’s a map with most UTF non-CJK characters (and includes mapping accents to latin form):
charset_table = non_cjk
