Printing and Displaying Dependent Vowels
We are in the process of updating Tamil keyboard drivers and one of the requirements by educational establishments is the ability to print and display dependent vowels without dotted circles. Can any one provide information on the sequences used for diplaying and printing dependent vowels as standalones. Srivas
printing dependent vowels
I'm looking for advice on how to print and display trailing vowels (dependent vowels) as stand alone characters in three different formats as described at http://www.araichchi.com/kanini/misal/print-trailing.pdf Srivas
tick, tick box, cross, cross box
We are in need of tick, tick box, crossand cross box preferably as symbols with code points. Any advice on this is appriciated SArivas
Tamil Unicode in Win 95 and 98.
Tamil Unicode in Windows 95 and 98. Now we can type, copy and paste within windows 95 and 98. Go to: http://www.jaffnalibrary.com/tools/Tsc.htm Click the button marked Unicode. Click in side the top box of the two boxes and start typing. Copy the Tamil text in the lower box. Paste into any application such as Word, OutlookExpress, etc... Way you go. Thanks to Suratha Sinnathurai Srivas Avarangal
Re: A case for Tamil-X (k sh)
As Michka wrote the matter (x , ksh) is being discussed elsewhere at present. Sorry it was typo: It should be ng in English (not en) and ng in penguin. I can't take my head off: keep saying rendering instead of complex rendering. I'll try.

A case for Tamil-X (k sh)
At INFITT WG02, a discussion is goin on about encoding x as a character and not as ligature. x is not always ksh. so rendering problem occurs, when one is chosen, the other is not possible. ie, with rendering enabled one can not have ksh, but only x. without rendering only ksh is possible and not x. Luxmi riksha are typical examples of different ways of writing and pronouncing. ie, the rendering system breaks. An analogy is en in English is a single consonant (though written as en), but en in penguin is two independent consonants. When ligaturing technique is used and assuming the ng has a single symbol then representing both e+n and en are not possible. Tamil only have one of these unusual character x. Others are practised a+b or ab depending on where it occurs in a word. But x has it's own form and k sh form in independently. hence there is a need to add a new Unicode character X for Tamil.
Documenting in Tamil Computing
fwd: fyi: Below is a copy of a mail I circulated on the subject of Documenting in Tamil Computing << From: "sisrivas <[EMAIL PROTECTED]>" <[EMAIL PROTECTED]> Date: Sun Dec 15, 2002 11:24pm Subject: Documenting in Tamil Computing We need to be clear as to the direction that Tamil is going with regard to Tamil computing. I'm writing this again and again as there is some miss understanding about what font encodings are doing to Tamil computing. (TSC is Temporary. TAB is temporary, OldType(alas Bamini) is temporary. 1/If you are preparing a Tamil document, intended for long term use you must use Unicode Encoding. Any other approach you take can be considered a waste of time if your content is intended for long term use.So do yourself and others a favour, prepare your documents using Tamil Unicode. see item 7 at the URL http://www.gbizg.com/Tamilfonts/ekalappai.htm on how to get Unicode keyboard drivers. Unfortunately Windows 95 and Windows 98 can only read Unicode pages. You can write in Unicode using Windows NT, 2000, XP and linux. So what can you do if you only have Windows 95, 98 or 3.1,Well sorry you need to use TSC or TAB or even OldType (alas Bamini) encoding. You can assume that these documents that you make will not be usable in the near future. Are you going to write a book, are you going to publish some research materials, etc, etc, do your self a favour. use Unicode and nothing else. DO NOT WASTE YOUR TIME. TIME IS PRESIOUS. 2/catch 22 You know we all use Tamil eMail and for that we can not use Unicode.For Tamil eMail we use 8bit encoding called TSCii. I'm sorry to say that you still need to use this 8 bit encoding (which is not Unicode), because Unicode is not mature enough to be used in multilingual email yet. You just have to make do with the 8bit TSCII encoding for Tamil eMail. For more infohttp://www.geocities.com/avarangal/ Sinnathuirai Srivas
Converting Pages to Unicode
Forwarding a question on converting to Unicode. <<< . Now I have a Question: As we can see, each web-site has different encodingand font. But I need to convert all encoding intoUnicode and display the content in IE, by justspecifying the encoding, which is unicode .. So for my research, i need to convert all the filesin all these web-sites into a single unicode-encoding. Additional Questions: When i wen through the web-sites i found somethinglike "x-user-defined". Can this user-defined be Unicode and 8bit? One more silly doubt.. is UTF-8 same as unicode, and can everything (8bit) be converted toUTF-8 (if it was easier). ... then please suggest a method to convert all diff pages from diffweb-sites into a single encoding and read it using asingle font. Thanks a lot, Kalairaja fwd: End

Re: Inherent "a"
Dear Doug Ewell, William Overington, James E. Agenbroad, and Maurice Bauhahn, Thank you all for the reply. May I assume u+0b85 as official? Some explanations for the need for a visible "a". In Tamil, a/ dependent "ai", and "au" has ligatures. infact "au" and "ou" at present utilise the same ligature. (Additionally the use of "ai and au" are expected to be introduced, not as ligatures.) b/ (dithong?) such as ae, ao need to be linearly represented (without ligatures) d/ The use of visible "a" for educational purposes with consonants are a necessity. e/ A design plan need to be implemented, anticipating the possible use of visible "a" instead of inherent "a" in the distance future. Regards Sinnathurai Srivas >> Avarangal I'm not sure why you want a character for a "inherent a" which, in Indic scripts, "exists"any consonant unmarked by a vowel sign or virama - perhaps you could describe your application. You could use 17B4 in the Khmer block. Since Khmer is also an Indic script, this character essentially has the properties you're looking for - though it's in a different block. - Another idea might be to use 0B85 (TAMIL LETTER A) + 093C (NUKTA) or maybe 0B85 + 0F9D (VIRAMA); - I don't know Tamil but I think these combinations would not normally occur. There was once a proposal to encode an "inherent a" or "root marker" at 0F70 in the Tibetan block as some people thought this was necessary as Tibetan syllables often contain silent prefixes and suffixes - but the primary collation is on the main letter in a syllable (which may be the second or third character in the string). In Tibetan the first consonant (or consonant stack) marked by a vowel sign is the root of a syllable - but where there is no vowel sign (i.e. an "inherent a") there is no "flag" to indicate the root consonant so some thought it would simplify processing to have one. A problem with this is that there would be no visible glyph for such a character and if the consonant marked by such an invisible character was deleted the inherent a character might get left behind and consequently flag an adjoining character where it might not be wanted. Also, since such a character is not necessary to display Tibetan properly, chances are you'd wind up with some people/ applications making use of this character and others not using it - so you'd get two different strings for the same word. In the case of Tibetan, the root consonant in a syllable or word can be determined by rules or a lookup - and in the end it was thought better to leave it to applications to determine unmarked root consonants when they needed to rather than having an inherent a character to mark them (which in any case would require a rule based system or lookup to insert reliably - unless you leave it to users to type in) . IMO in general use such a character would probably cause more problems than it solved - though it might sometimes be useful in private data. - Chris >>> > > While we're waiting for someone with better knowledge of Indic scripts > to reply... > > 1.

Inherant "a"
I need to allocate a U+codepoint for inherent "a", to be used for Tamil research. Can anyone suggest a temporary location or is it possible to find such code point within the existing code point for Tamil.
