Here are the facts. More at <http://www.adobeforums.com>, that goes to <http://www.adobe.com/support/forums/main.html> and then click "Adobe Acrobat Mac" and then the message "Cannot mark text with highlighter tool (yellow fluorescent marker) of Acrobat Pro 7.02 on Mac OS X". In short: pdfText generates PDF files that have the following bug: I can select and mark text on such PDF files with the highlighter tool (sort of yellow fluorescent marker) the very first time that I open a document. Yet, the next time in a row, it is not possible (instead the text below is selected and yellow-marked in an erratic way. Tested with Acrobat Pro 7.02 on Mac OS X 10.3.9. Try with this file: http://www.boe.es/boe/dias/2005-07-01/pdfs/A23458-23458.pdf The culprit is pdfTeX, as explained in the Adobe Forum indicted above: ----- I examined the file internally, and it claims to have been made by pdfTeX version 3.14159-1.10b. It also messes up other information. Creator (which should be the name of the software designing the page) is a filename. Author, which should have been BOE, is blank. To anyone who knows PDF, this sort of thing will ring alarm bells! ----- Note: the workaround is to open the file with Adobe Acrobat Pro and then: Advanced>Accessibilty>Add Tags to document. If possible, please this annoying bug so that PDF files created withpdfTeX do not have such problem. Thanks. ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=384&group_id=106

I applied it, but I do not have a lot of documents that need more than a few words of pdf_mem, so I changed the compile-time lower limit to 100. Works fine on my test documents. ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=495&aid=366&group_id=106

Back to Bernd's current e-mail: > Mmmh, what is the result when existing csnames are "overwritten" by > \expose... or when the meaning of an internal csname is assigned to > another csname by \let and then obscured? In general, if a macro progammer wants to be irresponsible, I'm not going out of my way to stop them from doing so. However, some of the more blatant user errors are easy to catch and I therefore propose to make them illegal from the start: \exposeinternal does not accept already defined <csname>s and \obscureinternal always makes the <csname> undefined > Here are some test cases ... > > \def\internalcommand{Hi!} > \begingroup > \exposeinternal\internalcommand A totally new error message is issued. Possibly ! Currently defined control sequence. \internalcommand ->Hi! But in this case perhaps even a stronger restriction is needed: ! Not at top level. > \obscureinternal\internalcommand > \show\internalcommand *\show\internalcommand > \internalcommand=undefined. > \begingroup > \exposeinternal\internalcommand > \global\let\x=\internalcommand > \endgroup > \show\x *\show\x > \x=\internalcommand. This is why the prefix is "obscure" instead of "undefine" > \exposeinternal\internalcommand > \let\x=\internalcommand > \obscureinternal\internalcommand > \show\x > \x=\internalcommand. > \exposeinternal\internalcommand > \def\x{\internalcommand} > \obscureinternal\internalcommand > \show\x > \x=macro: ->\internalcommand. > \x ! Undefined control sequence. \x ->\internalcommand > > Best wishes, > -bernd
