Re: [WebERP-developers] PDF generator in webERP.

Hi Andrew,
Sorry, just I read you messages.
Yes, as I said in previous messages, this new AddTextWrap fixes the extra
blank line bug. But if any user like this extra blank line bug, there is
lot of work adding a extra line to reports.
About the problem with your text:
I think the text does not wrap because it is using a non-breaking space
character instead of a white space character.
A possible fix:
$nbsp = html_entity_decode(' ', ENT_QUOTES, 'UTF-8');// Converts
non-breaking space HTML entity to their applicable character.
$text = str_replace($nbsp,' ',$text);
Best regards, Rafael.
