qingfengzealot has asked for the wisdom of the Perl Monks concerning the following question:

Hi, Monks I wonder if there is any way to print a superscript comma. I've tried Unicode::Subscript, but there is no way to get the comma in a superscript way. Anyone can help me? Thanks very much. Best regards, QY

    print "<sup>,</sup>\n";

    works for me, but maybe that isn't what you want. Maybe you need to give us more context?

    Is there a superscript comma? I donít see one in here: Unicode subscripts and superscripts. I have no idea of some combining characters would allow for it. Printing the simple characters from the blocks in that link is pretty simpleĖ

    perl -CSD -e 'print " x" . chr($_) for 0xB2, 0xB3, 0x2070 .. 0x207F; print $/'
     x≤ x≥ x⁰ xⁱ x⁲ x⁳ x⁴ x⁵ x⁶ x⁷ x⁸ x⁹ x⁺ x⁻ x⁼ x⁽ x⁾ xⁿ
    
      Yes, I also cannot find a superscript comma in Unicode subscripts and superscripts. I think there should be a way to print this in PERL, whatever modules, if it works, please let me know. Thanks.

    Is there any chance you're actually looking to print an apostrophe... which, in some fonts, looks something like a "superscript comma"?


    If you didn't program your executable by toggling in binary, it wasn't really programming!

      Hi, I'm definitely looking for "superscript comma" rather than an apostrophe. It is commonly used in the authorship list for publications. We have hundreds of scientists with different affiliations, I want to use script to generate them instead of manually type them one by one. Now, I'm using PERL script to read from ".csv" and write to a ".rtf" file. Something like the author list in the following article: http://www.nature.com/nature/journal/v496/n7443/pdf/nature12031.pdf Sorry, I don't know how to upload a picture. If you cannot open this article, please let me know you email address and I can send it to you. I also attached my script here, hope someone can help me. Thanks very much.
      #!/usr/bin/perl -w use strict; use warnings; use RTF::Writer; use Unicode::Subscript ':all'; use Text::CSV; #use Unicode::Subscript qw(subscript superscript); if(@ARGV != 2) { print STDERR "Usage: authorship_APP.pl input(.csv) output(.rtf)\n" +; exit(0); } my ($inf, $outf)=@ARGV; my $all_affi; my %hash; my @all_name; my $count=1; my @rows; my $csv = Text::CSV->new ( { binary => 1 } ) # should set binary attr +ibute. or die "Cannot use CSV: ".Text::CSV->error_diag (); open my $fh, "<", $inf or die "$inf: $!"; while ( my $row = $csv->getline( $fh ) ) { if($row->[0]=~/^\d/){ my @a_num; for(my $i=3; $i<=7; $i++){ if($row->[$i]=~/\w/){ my $tmp=$row->[$i]; if(! exists $hash{$tmp}){ $hash{$tmp}=$count; push(@a_num, $hash{$tmp}); $all_affi.=$count.$tmp."\. "; $count++; } }else{ last; } } my $a_num=join"\+", @a_num; if($row->[2]=~/\w/){ push(@all_name, "$row->[1] $row->[2]".superscript($a_num)) +; }elsif($row->[1]=~/\w/){ push(@all_name, "$row->[1]".superscript($a_num)); }else{ print STDERR "Error! Wrong first name for this row:\n$row\ +n"; exit; } } } $csv->eof or $csv->error_diag(); close $fh; my $all_name=join", ", @all_name; print STDERR "There are ". scalar(@all_name)." authors and ".scalar(ke +ys %hash)." affiliations in this list.\n"; my $final= "$all_name\n\n$all_affi\n"; #my $test='This algorithm is O(n' . superscript(3) . ')'; my $rtf = RTF::Writer->new_to_file($outf); $rtf->prolog( 'title' => "Greetings, Naomi" ); $rtf->number_pages; $rtf->paragraph( $final ); $rtf->close;
        I should mention that there is no need to rely on ".rtf" file. If there are any ways to generate the authorship list (including the superscrtipt comma) and could let me copy the context to microsoft word (.doc) file, it would be fine... Whatever format the output is... Thanks.

        I believe those characters you are thinking of as superscripts in the pdf document are actually just regular characters being displayed in a different font and different baseline. See this short discussion from stackoverflow. So you won't be able to get all the information into the plain text, instead you'll have to somehow encode the proper font formatting to send along with the text. Presumably the 'font' method in RTF::Writer might help do the job. But other monks may have better ideas.

    There is http://search.cpan.org/~sburke/RTF-Writer/lib/RTF/Cookbook.pod which is useful in this context. I compiled a small example, which creates a file super.rtf that has superscripts with commata.

    use strict; use warnings; use RTF::Writer; my %authors = ( "Isheng J. Tsai" => "1,2", "Magdalena Zarowiecki" => "1", "Nick Riddiford" => "14,15", ); my $rtf = RTF::Writer->new_to_file( "super.rtf" ); $rtf->prolog( title => "Authors" ); $rtf->paragraph( \'', "The authors:" ); for my $a (sort keys %authors) { $rtf->print( \'\plain', "$a" ); $rtf->print( \'\super', $authors{$a} ); $rtf->print( \'\plain', "," ); } $rtf->close;
