Hi,

 

I am new to the OpenType tables and Volt. I am trying to create a new Telugu OpenType font. I would greatly appreciate any information on creating telugu fonts.

 

Also is the following something I should look at ?

http://www.microsoft.com/typography/OpenType%20Dev/telugu/intro.mspx

Has there been any update to this ?

 

Also the following site gives two script tags

http://www.microsoft.com/typography/otspec150/scripttags.htm

 

Telugu	telu
Telugu v.2	tel2

 

Are the differences between these two documented somewhere ? Which one of them is preferred or should I support both of them.

 

Thanks a lot

Does Telegu have any vowel sign that (or part of it) appears to the left of the base consonant? If so, then some updates to Indic Uniscribe are applicable to you which are not yet documented.

 

Search the message board for the topic Devanagari & new features (started by Manitoshi, last reply 6-Oct-2006 9:24pm). PeterCon explained the undocumented updates in his first set of replies.

Thank you for  your response.

 

It appears that Telugu is different from Devanagari in this regard. I would greatly appreciate if PeterCon or someone else could give us the differences between tel and tel2.

Hi, Seattle0.

I am too interested in a Telugu font. The layout of the Telugu alphabet is very similar to other Indian alphabets. They are all based on phonology rules by rishi Panini. I have made a smartfont for Classic Sinhala (CS) which is similar to Telugu. This is world's frst smart font for any non-Latin based language that has a native script. It is a huge success.

You (as a business partner) could use my font as the foundation to make one for Telugu. Mostly, you change the shapes of the letters in the font from Sinhala to Telugu in the corresponding places and add a few that CS lacks and you get a fast typing font. We would do a few additions to and many subtractions from the font tables. (Sinhala is much complex that other Indic having multiple orthographies).

The smartfont uses the US-International keyboard (extended US-English) instead of  the Indic keyboard. That makes input extremely easy and intuitive to type while you get the complex Indic letters automatically selected for you with orthographic precision. More importantly, it makes the language universally usable avoiding limitations of double-byte code.

Go to the following link and see the font displaying the underlying Latin code in complex Sinhala forms. The text is Sinhala intermingled with Sanskrit::

Sorry, it is telu vs tel2

http://www.microsoft.com/typography/otspec150/scripttags.htm

lists tel2 as a telugu v.2 script tag. In fact all Indian languages seem to have a v.2 script tag. I would like to understand what the difference is between telu and tel2.

 

When I searched the only thing I found was the following fontforge mailing list discussion.

http://osdir.com/ml/fonts.fontforge.devel/2006-09/msg00012.html

MS has made substantial (and incompatible) changes to the way
        Indic glyphs are reordered and shaped. The same features are
        used, but they now mean different things (or something... I
        didn't pay as close attention as I should).
       
        In order to avoid confusion MS has created a new set of script
        tags for each affected writing system:
                Bengali      beng       bng2
                Devanagari   deva       dev2
                Gujarati     gujr       gjr2
                Gurmukhi     guru       gur2
                Kannada      knda       knd2
                Malayalam    mlym       mly2
                Oriya        orya       ory2
                Tamil        taml       tml2
                Telugu       telu       tel2
        So it is possible to design a font which will work with the old
        shaping engine and the new by having both scripts (and
        appropriate features) in GSUB/GPOS.
       
        FontForge has these new tags in its script dialog, and has a
        preference item to control which is used by default.

Hi

 

Sorry. My reply is late by 7 months. Today only I saw your post accidentally.

 

Microsoft started a new tag names for script and language system. For a detailed explanation please see : http://www.microsoft.com/typography/otfntdev/teluguot/appen.aspx

 

While I am creating my font what I experienced is 'tel2' is required for Vista system whereas for XP it is 'telu'. The look ups are slightly different in both these. For 'telu' the Vattu look up looks like -- consonant halanth -> consonantvattu. Whereas for 'tel2' the look up is --- halanth consonant -> consonantvattu. It took me five six days to figure out this and Mr. Stephene from France helped me in this respect.

 

I posted my telugu font today.

Microsoft created these 'tel2', 'dev2' ... in order to fix a problem they had involving pre-matra (like the u093F character in devanagari) interacting with consonants that do not have a half form.

Since none of these features exist in Telugu (not half forms for consonants, not pre-vowel), telugu should not have been affected by these changes.

Yet in order to make their engine more coherent I guess Microsoft updated all the indic scripts at once. In the case of Telugu, the only changes I know of, is that the order of the sequence are reserved between "telu" and "tel2" open type specifications, as M. Venu Gopal explained earlier.

 

Under Windows Vista, Notepad uses "tel2" if it can find the description in the font, otherwise it will revert to "telu". At the moment very few fonts uses the new specifications (apart from the new Gautami that is shipped with Windows Vista). I don't think OpenOffice has updated its engine to support these new tags.
