encoding the ® character

My scenario is that I am generating dcrs based on the output from a database query.

I have recently found that some of the generated dcrs which contain the ® character will not compile. I was getting the error message - Invalid byte 1 of 1-byte UTF-8 sequence.

I have encoded "®" using HTML::Entities::encode(HTML::Entities::decode($item), "\<\>\&\|\`\®"); . I am now getting the error message - The entity "reg" was referenced, but not declared.

Any advise on how to declare the entity "reg"

I have tried to encode "reg" using the folllowing;

with no success.

Try writing "& r e g ;" in place of your ® character. Just remove the spaces, I added becasue it was not printing in page.

I have overcome this solution by using CGI_Lite module in Perl. It has 2 methods like escape_html_data and unescape_html_data.

It just converts any special character to its html entity code and vice-versa. I hope this suits your requirement.

Hi There,

You can use ®

Please take a look at this url for other chars...

What i understood from the query is need of encoding and decoding of the ® mark and it definitely uses some methods to do that.

However you can also catch and replace the ® mark with ® using regular expressions. To mention not a good solution to do.

I've used =~ tr/®/®/; but everything after & is being ignored, I reckon b/c of the #.

I've used =~ tr/®/®/; but everything after & is being ignored, I reckon b/c of the #.

To use the transliterate (tr//) function I believe you would have to do something using one of the special escape sequences (for octal, hex, control, or named unicode characters).

I think what you are probably trying to do (it's difficult to tell from here since all the code seems to be getting interpreted and showing the registered trademark character instead of the verbatim code you are trying to use) - the subtitution (s///) function is more likely to be of help.

(see perldoc perlop and/or perldoc perlre for more information)

I think this will also depend on the locale setting on the server.
