Dear caml-list, We are working on improving unicode support in zed, lambda-term and utop. These new improvements retrofit the concept of what the essential element should be, from UChar.t, an individual unicode character to Zed_char.t, a new type representing a glyph in the unicode standard. So non-latin script and combined glyphes will be better supported. For more information and the preview releases of these projects, see https://github.com/ocaml-community/lambda-term/issues/2#issuecomment-487348878
