<html> <head> <meta content="text/html; charset=UTF-8" http-equiv="Content-Type"> </head> <body bgcolor="#FFFFFF" text="#000000"> Just my two cents from my days at NeXT and Apple: If Adobe were concerned with violating copyright issues with Fonts they never would have released the ISOs for PDF to the general public. You can't have your cake and eat it too. You want PDF to be ubiquitous but then you want to hen peck every Tom, Dick and Harry on licensing third party fonts? Are you authorized to speak for Monotype? Or any other Font Author? Font Portfolios licensed to corporations is a lucrative business. Attempting to police this on an individual who has a document they want to convert to html is asking for a Xerox ruling on Photocopying and your IP becoming so common it becomes worthless. By all means, go after millions of users who extract fonts from PDF documents having embedded fonts in them. Put excessive DRM schemes on your solution. Watch your entire intent of making PDF ubiquitous go down in flames. Adobe better find some other way to leverage their Font technology for profit that is a value added service in n-tier markets or watch your customer base completely erode. This finger waging about Fonts reminds me of that finger waving about Display Postscript and we decided to create Display PDF instead. - Marc On 09/22/2011 03:08 PM, Leonard Rosenthol wrote: <blockquote cite="mid:CAA129BB.C345%25lrosenth@adobe.com" type="cite"> <pre wrap="">I can't recall what you said about this in the past, but since I was just dealing with it today.

This produces the correct visual result in the XHTML, but not a full semantic representation. If someone's interested, they could get the semantics right too by pattern-matching the glyph against an appropriate Unicode font. W.r.t. the flow of text, there have been other threads on this topic, but pdftohtml does make some attempt, and I believe it's possible to do this to a high degree of accuracy, maybe >99% -- that said, noone has done it yet, so either it's harder than I think, or no-one has cared enough to really try (and I still fall into that camp.)
