Minicom is unable to display UTF-8 characters in its own menu dialogs. My locale is cs_CZ.UTF-8, try to enter configuration dialog (press CTRL+a).
*** Bug 81694 has been marked as a duplicate of this bug. ***
Adding support for UTF8 to minicom is difficult for us, because it uses its own function for printing and managing window (scrolling, line breaking and so on...). Adding support for UTF8 means rewriting big parts of window.c and it causes incompatibility with upstream package (e.g. UTF8 uses different size of characters, minicom uses only one byte chars...). This issue has been reported to upstream.
