Dear All,
</div>
<div>
<span style="font-size: 9pt;"> </span>
</div>
<div>
<span style="font-size: 9pt;">As discussed, please find attached, the proposed text that both the Odia (Oriya) and Malayalam teams may consider adding to their respective LGR documents towards justifying the inclusion of the single character Consonant TTHA as variant. </span>
</div>
<div>
<span style="font-size: 9pt;"> </span>
</div>
<div>
<span style="font-size: 9pt;">I have added both the following aspects in the current reasoning:</span>
</div>
<div>
<span style="font-size: 9pt;">1. Relatedness of the scripts and thereby limiting the scope only to the NBGP scripts</span>
</div>
<div>
<span style="font-size: 9pt;">2. Impracticality of carrying out the cross-script variant analysis between all the script under the Root LGR procedure.</span>
</div>
<div>
<span style="font-size: 9pt;"> </span>
</div>
<div>
<span style="font-size: 9pt;"> </span>
</div>
<div>
<span style="font-size: 9pt;">Regards,</span>
</div>
<div>
<span style="font-size: 9pt;">Akshat</span>

<p><span style="font-family: Georgia;">Dear All,</span></p>
<p><span style="font-family: Georgia;">As discussed in yesterday's call, here is the proposed text that both the Odia (Oriya) and Malayalam teams may consider adding to their respective LGR documents towards justifying the inclusion of the single character Consonant TTHA as variant. Please go through the text carefully. I have included implicit agreement with the subsequent IP decision on the same. Whether to add the same or not can be discussed on the call later today. <br/> </span></p>
<p><span style="font-family: Georgia;"><em>---%Te</em><em>xt begin</em><em>s</em><em>%----</em><br/> </span></p>
<p><span style="font-family: Georgia;"><strong>NBGP Cross-script Variant inclusion policy:</strong></span></p>
<p><span style="font-family: Georgia;">If, in any two given scripts, all the potential cross-script variants consist of dependent (e.g. Vowel Signs, Anusvara, Visarga, Chandrabindu etc) characters <strong>ONLY</strong>, then that entire set can be ignored and no cross-script variants be proposed between those two scripts. <br/> </span></p>
<span style="font-family: Georgia;"> If, in any two given scripts, there is <strong>AT LEAST ONE</strong> non-dependent (e.g. Consonant, Vowel etc) cross-script variant character/sequence present, all the potential cross-script variants be considered and proposed between the two scripts.</span>
<span style="font-family: Georgia;"><br/> <br/> <strong><br/> Case of </strong><strong>Malayalam and Odia (Oriya) TTHA Consonant:</strong><br/> <br/> There are two proposed single character cross-variants between Malayalam and Odia, those are:</span>
<p><span style="font-family: Georgia;">ഠ - MALAYALAM LETTER TTHA (U+0D20)<br/> ଠ - ORIYA LETTER TTHA (U+0B20)<br/> </span></p>
<p><span style="font-family: Georgia;">Both the characters, look exactly alike and belong to a "Consonant" category. As they are consonants, each of them, even in the simplest form i.e. the characters themselves, are valid labels. As per the NBGP cross-script variant inclusion policy, this is a valid case for inclusion. Also, even if they are single characters, when the same character combines, theoretically they can form infinite* number of cross-script variant labels between the scripts involved. Here are some samples of some of those labels:</span></p>
<table style="width: 708px;" cellpadding="2" border="1" cellspacing="2"><tbody><tr><td valign="top"><span style="font-family: Georgia;">Malayalam<br/> </span></td><td valign="top"><span style="font-family: Georgia;">Oriya <br/> </span></td></tr><tr><td valign="top"><span style="font-family: Georgia;">ഠഠഠ<br/> U+0D20 U+0D20 U+0D20<br/> </span></td><td valign="top"><span style="font-family: Georgia;">ଠଠଠ<br/> U+0B20 U+0B20 U+0B20 <br/> </span></td></tr><tr><td valign="top"><span style="font-family: Georgia;">ഠഠഠഠ<br/> U+0D20 U+0D20 U+0D20 U+0D20 </span></td><td valign="top"><span style="font-family: Georgia;">ଠଠଠଠ<br/> U+0B20 U+0B20 U+0B20 U+0B20 <br/> </span></td></tr><tr><td valign="top"><span style="font-family: Georgia;">ഠഠഠഠഠ<br/> U+0D20 U+0D20 U+0D20 U+0D20 U+0D20 </span></td><td valign="top"><span style="font-family: Georgia;">ଠଠଠଠଠ<br/> U+0B20 U+0B20 U+0B20 U+0B20 U+0B20 <br/> </span></td></tr></tbody></table>
<p><span style="font-family: Georgia;">Since, having such labels is a realistic possibility and the corresponding labels look almost exactly alike, NBGP has proposed them as blocked variants. NBGP also understands that this shape is quite generic and may have parallels in other scripts not under the ambit of NBGP. Since NBGP does not have any exposure in terms of actual usage of those characters in those particular scripts, NBGP desisted from including them. However, by proposing them as "blocked" variants, NBGP has taken the most conservative approach, which is ingrained in the LGR procedure. If, in future, this recommendation is in conflict with any other new script being added to the RZ-LGR, it is envisioned that the most conservative approach would prevail and the recommendation of blocking would still hold good**.<br/> </span></p>
<p><span style="font-family: Georgia;">* Though theoretically infinite, this number would be limited to the number of such labels whose equivalent punycode string would not exceed 63 characters including the ACE prefix "xn--".<br/> </span></p>
<p><span style="font-family: Georgia;">** NBGP however, understands that the final decision of including the same in the cross-script variant set, depends on the Integration Panel and plans to abide by it. <br/> </span></p>
