Just replace the %c with %1s and that will take care of scanf reading the newline in the input...
Code:
scanf("%1s", &w);

Code:
c                      A character is expected; the corresponding argument
                       should be a character pointer.  The normal skip-
                       over-white-space is suppressed in this case; to read
                       the next non-space character, use %1s.  If a field
                       width is given, the corresponding argument refers to
                       a character array; the indicated number of characters
                       is read.

NAME
paps - UTF-8 to PostScript converter using Pango SYNOPSIS
paps [options] files... DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves through the pango ft2 backend. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. --landscape Landscape output. Default is portrait. --columns=cl Number of columns output. Default is 1. --font=desc Set the font description. Default is Monospace 12. --rtl Do rtl layout. --paper ps Choose paper size. Known paper sizes are legal, letter, a4. Default is A4. --bottom-margin=bm Set bottom margin in postscript points (1/72 inch). Default is 36. --top-margin=tm Set top margin. Default is 36. --left-margin=lm Set left margin. Default is 36. --right-margin=rm Set right margin. Default is 36. --help Show summary of options. --header Draw page header for each page. --markup Interpret the text as pango markup. --encoding=ENCODING Assume the documentation encoding is ENCODING. --lpi Set the lines per inch. This determines the line spacing. --cpi Set the characters per inch. This is an alternative method of specifying the font size. --stretch-chars Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops behaviour. AUTHOR
