+.SH DESCRIPTION
+.SS Adding characters
+The \fBaddch\fR, \fBwaddch\fR, \fBmvaddch\fR and \fBmvwaddch\fR routines put
+the character \fIch\fR into the given window at its current window position,
+which is then advanced.  They are analogous to \fBputchar\fR(3) in \fBstdio\fR(3).
+If the advance is at the right margin:
+.bP
+The cursor automatically wraps to the beginning of the next line.
+.bP
+At the bottom of the current scrolling region,
+and if \fBscrollok\fR is enabled,
+the scrolling region is scrolled up one line.
+.bP
+If \fBscrollok\fR is not enabled,
+writing a character at the lower right margin succeeds.
+However, an error is returned because
+it is not possible to wrap to a new line
+.PP
+If \fIch\fR is a tab, newline, carriage return or backspace,
+the cursor is moved appropriately within the window:
+.bP
+Backspace moves the cursor one character left; at the left
+edge of a window it does nothing.
+.bP
+Carriage return moves the cursor to the window left margin on the current line.
+.bP
+Newline does a \fBclrtoeol\fR,
+then moves the cursor to the window left margin on the next line,
+scrolling the window if on the last line.
+.bP
+Tabs are considered to be at every eighth column.
+The tab interval may be altered by setting the \fBTABSIZE\fR variable.
+.PP
+If \fIch\fR is any other control character, it
+is drawn in \fB^\fR\fIX\fR notation.  Calling \fBwinch\fR after adding a
+control character does not return the character itself, but instead returns
+the ^-representation of the control character.
+.PP
+Video attributes can be combined with a character argument passed to
+\fBaddch\fR or related functions by logical-ORing them into the character.
+(Thus, text, including attributes, can be copied from one place to another
+using \fBinch\fR(3X) and \fBaddch\fR.)  See the \fBattr\fR(3NCURSES) page for
+values of predefined video attribute constants that can be usefully OR'ed
+into characters.
+.SS Echoing characters
+.PP
+The \fBechochar\fR and \fBwechochar\fR routines are equivalent to a call to
+\fBaddch\fR followed by a call to \fBrefresh\fR(3X), or a call to \fBwaddch\fR
+followed by a call to \fBwrefresh\fR.  The knowledge that only a single
+character is being output is used and, for non-control characters, a
+considerable performance gain may be seen by using these routines instead of
+their equivalents.
+.SS Line Graphics
+The following variables may be used to add line drawing characters to the
+screen with routines of the \fBaddch\fR family.  The default character listed
+below is used if the \fBacsc\fR capability does not define a terminal-specific
+replacement for it,
+or if the terminal and locale configuration requires Unicode but the
+library is unable to use Unicode.
+.PP
+The names are taken from VT100 nomenclature.

+.SH RETURN VALUE
+All routines return the integer \fBERR\fR upon failure and \fBOK\fR on success
+(the SVr4 manuals specify only
+\*(``an integer value other than \fBERR\fR\*('') upon successful completion,
+unless otherwise noted in the preceding routine descriptions.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.SH NOTES
+Note that \fBaddch\fR, \fBmvaddch\fR, \fBmvwaddch\fR, and
+\fBechochar\fR may be macros.
+.SH PORTABILITY
+All these functions are described in the XSI Curses standard, Issue 4.
+The defaults specified for forms-drawing characters apply in the POSIX locale.
+.SS ACS Symbols
+.LP
+X/Open Curses states that the \fIACS_\fP definitions are \fBchar\fP constants.
+For the wide-character implementation (see \fBcurs_add_wch\fP),
+there are analogous \fIWACS_\fP definitions which are \fBcchar_t\fP constants.
+.LP
+Some ACS symbols
+(ACS_S3,
+ACS_S7,
+ACS_LEQUAL,
+ACS_GEQUAL,
+ACS_PI,
+ACS_NEQUAL,
+ACS_STERLING)
+were not documented in
+any publicly released System V.  However, many publicly available terminfos
+include \fBacsc\fR strings in which their key characters (pryz{|}) are
+embedded, and a second-hand list of their character descriptions has come
+to light.  The ACS-prefixed names for them were invented for \fBncurses\fR(3NCURSES).
+.LP
+The \fIdisplayed\fP values for the \fIACS_\fP and \fIWACS_\fP constants
+depend on 
+.bP
+the library configuration, i.e., \fBncurses\fP versus \fBncursesw\fP,
+where the latter is capable of displaying Unicode while the former is not, and
+.bP
+whether the \fIlocale\fP uses UTF-8 encoding.
+.LP
+In certain cases, the terminal is unable to display line-drawing characters
+except by using UTF-8 (see the discussion of \fBNCURSES_NO_UTF8_ACS\fP in
+ncurses(3X)).
+.SS Character Set
+X/Open Curses assumes that the parameter passed to \fBwaddch\fP contains
+a single character.
+As discussed in \fBcurs_attr\fP(3X), that character may have been
+more than eight bits in an SVr3 or SVr4 implementation,
+but in the X/Open Curses model, the details are not given.
+The important distinction between SVr4 curses and X/Open Curses is
+that the non-character information (attributes and color) was
+separated from the character information which is packed in a \fBchtype\fP
+to pass to \fBwaddch\fP.
+.PP
+In this implementation, \fBchtype\fP holds eight bits.
+But ncurses allows multibyte characters to be passed in a succession
+of calls to \fBwaddch\fP.
+The other implementations do not do this;
+a call to \fBwaddch\fP passes exactly one character
+which may be rendered as one or more cells on the screen
+depending on whether it is printable.
+.PP
+Depending on the locale settings,
+ncurses will inspect the byte passed in each call to \fBwaddch\fP,
+and check if the latest call will continue a multibyte sequence.
+When a character is \fIcomplete\fP,
+ncurses displays the character and moves to the next position in the screen.
+.PP
+If the calling application interrupts the succession of bytes in
+a multibyte character by moving the current location (e.g., using \fBwmove\fP),
+ncurses discards the partially built character,
+starting over again.
+.PP
+For portability to other implementations,
+do not rely upon this behavior:
+.bP
+check if a character can be represented as a single byte in the current locale
+before attempting call \fBwaddch\fP, and
+.bP
+call \fBwadd_wch\fP for characters which cannot be handled by \fBwaddch\fP.
+.SS TABSIZE
+.LP
+The \fBTABSIZE\fR variable is implemented in some versions of curses,
+but is not part of X/Open curses.
+.LP
+If \fIch\fR is a carriage return,
+the cursor is moved to the beginning of the current row of the window.
+This is true of other implementations, but is not documented.
