<div>2007/2/2, Rajeev J Sebastian <<a href="mailto:rajeev.sebastian@gmail.com">rajeev.sebastian@gmail.com</a>>:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> The model for some languages are changing as well. It is entirely possible that Fallback Rendering will be removed for Malayalam and perhaps other scripts or characters of scripts as well. So, the specs may change yet again, and quite soon too. </blockquote><div> As far my experiance with Indic fonts, and rendering goes, errors dont lie at one place. Mostly their root cause hides in the specifications that are being followed(this applies specially to malayalam and oriya). Reasons I spot for some still alive bugs are: 1. Ambiguous/wrong specification for few indic languages in Microsoft's OpenType specs(up to XP at least) 2. Adaptation of these standards by Font developers 3. Some mistaken implementations in current rendering engines(specially Pango/ICU) 4. And finally disagreements within specific language communities regarding these specs and general use of language(most I noted was malayalam). When you correct few things in renderer regardless the specifications provided by Microsoft, few fonts will break, only because they were based on those specs. And since we don't have clean and really *open* specs, this only adds to the problem. Thus my suggestion for Indic rendering would be to either wait for Vista's specs to come out, or redefine the specs for indic languages involving the communities from all the languages and font developers. Use these specs for Linux platform and let the developers follow these new standards. Second option would be in my preference. Maybe this would be a big step, I'm really not sure, but it will avoid any further problems at least at the rendering engine level. Thanks & Regards, Rahul Bhalerao. </div></div>
