Questions re the recognition of URLs in text when the option to "Create links from URLs" is enabled

[stephenm87817100]

I am looking for advice on what format of text is converted by the option to create links from URLs.

So far I have discovered that the following forms of text (rendered using Tj and TJ operators) are converted to links:

anytext://anytext

www.anytext

fred@widget.com

but not:

widget.com

Are there any other formats of text that are recognised as links?

In Tj and TJ operators, the content is actually glyph indices into the current font, but at least with hyperlinks, the glyph indices are generally the same as the rendered text, eg: (www.babc.com)Tj

Does the recognition of hyperlinks get applied to the un-rendered operand(s) of the text rendering operator, or is the recognition applied to the rendered text, after the glyph indices have been resolved using the current font?

Apart from Tj and TJ operators appearing in page content, is there any other context within a PDF document where links are created from text that appears to be a URL?

Thanks

Steve

I should explain that I am tasked with ensuring that text sequences written into a PDF are disrupted to ensure the text is NOT interpreted as a hyperlink by the end user's PDF reader, as we have no control over whether the end user has disabled the "Create links from URLs" option.

Any help with the questions above would be really appreciated.
