Assuming above thoughts to be true, try
Code:
awk '
        {if ($1 ~ "<\/?s>") ST = NR
         else   {$1=$1 OFS tolower($1)
                 $3=NR-ST
                }
        }

This solution words great for ascii characters. However, I have some characters that are non-ascii and they do not convert correctly when using
Code:
 tolower

. For instance, this is what happened:

Code:
<s>
Pero	pero	cc	0
lo	lo	da0000	1
más	m?s	rg	2
importante	importante	aq0000	3
,	,	fc	4
no	no	rn	5
sólo	s?lo	rg	6
desde	desde	sp000	7
la	la	da0000	8
visión	visi?n	nc0s000	9
de	de	sp000	10
una	una	di0000	11
parte	parte	nc0s000	12
</s>

Is there a way to maintain the non-ascii character when using
Code:
 tolower

?

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
