If sentence is UTF-8 or UTF-16, you should explicitly use sequence utf32 = utf8_to_utf32(string utf8) or sequence utf32 = utf16_to_utf32(sequence utf16) before any slicing or find()/match(), and string utf8 = utf32_to_utf8(sequence utf32) or sequence utf16 = utf32_to_utf16(sequence utf32) before display. Note that unicode does not normally display correctly on a standard Windows console, but is fine in a GUI or Linux console or a web browser.
