Yes, I know the sort of think you mean now - when using Word I remember
having the option to open a complicated looking dialog box that allowed me
to insert characters like the copyright and trademark symbols. I would have
expected that if they could be placed into a Word document then they are
encoded somewhere and available to us. My only doubts here surround Words
use of Unicode - if it uses Unicode then everything should be OK.
Also, I made another discovery tonight whilst playing with some code. If you
remember my previous post, I got the CharacterRun(s) from the documents high
level Range object. This does not have to be the case. You can do something
like this;
HWPFDocument doc = new HWPFDocument(new FileInputStream(new
File("C;\\temp\\test.doc")));
Range = doc.getRange();
int numParagraphs = range.numParagraphs();
for(int i = 0; i < numParagraphs; i++) {
Paragraph para = range.getParagraph(i);
int numCharRuns = para.numCharacterRuns();
for(int j = 0; J , numCharRuns; j++) {
CharacterRun charRun = para.getCharacterRun(j);
..........
}
}
That would allow you to create new paragraphs ini the pdf file when you need
to - if I remember correctly, pdf files contain markedup text organised inot
paragraphs with the /par tag - and build each from the contents of the
character runs.
