sed command works from cmd line to standard output but will not write to file
Hi all .... vexing problem here ...

I am using sed to replace some special characters in a .txt file:

sed -e 's/_<ED>_/_355_/g;s/_<F3>_/_363_/g;s/_<E1>_/_341_/g' filename.txt

This command replaces <ED> with í , <F3> with ó and <E1> with á.

When I run the command to standard output, it works as expected.

When I attempt to write to another file, the special characters are eliminated again.

so
sed -e 's/_<ED>_/_355_/g;s/_<F3>_/_363_/g;s/_<E1>_/_341_/g' filename.txt

works, but

sed -e 's/_<ED>_/_355_/g;s/_<F3>_/_363_/g;s/_<E1>_/_341_/g' filename.txt>filename2.txt

does not.

any help is appreciated.

extract_font_range(3alleg4)					  Allegro manual				       extract_font_range(3alleg4)

NAME

       extract_font_range - Extracts a range of characters from a font. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       FONT *extract_font_range(FONT *f, int begin, int end)

DESCRIPTION

       This  function  extracts  a  character range from a font and returns a new font that contains only the range of characters selected by this
       function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or  to  the  end  of  the
       font.  Example:

	  FONT *myfont;
	  FONT *capitals;
	  FONT *fontcopy;
	  ...
	  /* Create a font of only capital letters */
	  capitals = extract_font_range(myfont, 'A', 'Z');

	  /* Create a copy of the font */
	  fontcopy = extract_font_range(myfont, -1, -1);
	  ...
	  destroy_font(capitals);
	  destroy_font(fontcopy);

RETURN VALUE

       Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it
       to avoid memory leaks.
