I stumbled upon a few typos in the sort order definitions: In Hebrew and Yiddish, there are many unclosed brackets: definitions['he'] = { 979 entries = { 980 ['א'] = 'א', ['ב'] = 'ב', ['ג'] = 'ג', ['ד'] = 'ד', ['ה'] = 'ה', 981 ['ו'] = 'ו', ['ז'] = 'ז', ['ח'] = 'ח', ['ט'] = 'ט', ['י'] = 'י', 982 ['כ'] = 'כ', ['ל'] = 'ל', ['מ'] = 'מ', ['נ'] = 'נ', ['ס'] = 'ס', 983 ['ע'] = 'ע', ['פ'] = 'פ', ['צ'] = 'צ', ['ק'] = 'ק', ['ר'] = 'ר', 984 ['ש'] = 'ש', ['ת'] = 'ת', 985 }, etc. Hraban
