Code:

#!/usr/bin/bash                      
while read line                      
do                                   
if [ "${line:0:1}" = "[" ]           
then                                 
        len=${#line}                 
        (( len = $len - 2 ))         
        outfile=${line:1:$len}       
        echo "$line" >$outfile.txt   
else                                 
        echo "$line" >>$outfile.txt  
fi                                   
done <inputfile                      
 cat *.txt >true_outfile

I ran this in an empty directory except for the input file, and the script.
You may find whatever application you are using this in will be simpler if you keep the intermediate files rather than the final file.

Code:

-bash-3.2# l                                                        
total 48                                                            
-rwxr-xr-x    1 root     sys        232 Oct 12 19:37 i              
-rw-r--r--    1 root     sys         76 Oct 12 19:03 inputfile      
-rw-r--r--    1 root     sys         76 Oct 12 19:37 true_outfile   
-bash-3.2# ./i                                                      
-bash-3.2# l                                                        
total 96

text::pdf::ttfont

Text::PDF::TTFont(3pm)					User Contributed Perl Documentation				    Text::PDF::TTFont(3pm)

NAME

       Text::PDF::TTFont - Inherits from Text::PDF::Dict and represents a TrueType font within a PDF file.

DESCRIPTION

       A font consists of two primary parts in a PDF file: the header and the font descriptor. Whilst two fonts may share font descriptors, they
       will have their own header dictionaries including encoding and widhth information.

INSTANCE VARIABLES

       There are no instance variables beyond the variables which directly correspond to entries in the appropriate PDF dictionaries.

METHODS

       Text::PDF::TTFont->new($parent, $fontfname, $pdfname, %opts)

       Creates a new font resource for the given fontfile. This includes the font descriptor and the font stream. The $pdfname is the name by
       which this font resource will be known throught a particular PDF file.

       All font resources are full PDF objects.

       $t->width($text)

       Measures the width of the given text according to the widths in the font

       $t->trim($text, $len)

       Trims the given text to the given length (in per mille em) returning the trimmed text

       $t->out_text($text)

       Indicates to the font that the text is to be output and returns the text to be output

       $f->copy

       Copies the font object excluding the name, widths and encoding, etc.

TITLE

       Text::PDF::TTIOString - internal IO type handle for string output for font embedding. This code is ripped out of IO::Scalar, to save the
       direct dependence for so little. See IO::Scalar for details
