And another refactor on that..

When PDCurses is built with wide-character support enabled, the narrow-character functions treat the string as a multibyte string in the current locale, and convert it first. All characters to the right of the cursor are moved to the right, with the possibility of the rightmost characters on the line being lost. The cursor position does not change (after moving to y, x, if specified). The routines with n as the last argument insert at most n characters; if n is negative, then the entire string is inserted. Return Value: All functions return OK on success and ERR on error.
