Tibetan Pinyin and Tongyong Pinyin do, as do other uses of Latin in romanizations used in China for Sino-Tibetan and other languages.<div><br></div><div>It is probable that Wade-Giles conventions were used for languages other than Mandarin, but the point is that we're looking to approve both "wadegile" and "pinyin" subtags here. </div><div><br></div><div>I'm not convinced that these subtags should be restricted as has been proposed to zh- or zh-Latn. Evidently there is some programmatic utility to keeping -Latn following whatever prefix (zh-, bo-) though I have yet to feel consensus amongst you as to whether zh-pinyin and zh-Latn-pinyin should both be "allowed". It seems to me that both are inevitable and that the revision should permit Suppress-script to be attached to subtags like fonipa/fonupa/pinyin to prevent the inevitable omission of -Latn-. But in any case I do believe that bo-(Latn-)pinyin is appropriately subtagged by "pinyin" and despite the fact that the requesters were only requesting Mandarin, there's more beneath the hood than that.</div><div><br></div><div>Either we have no Prefix at all or we list a set of prefixes that we know at present can be used with the subtag and presumably add more in future.</div><div><br></div><div>Sorry Mark and Peter for the delay but this really does need to be done right.</div><div><div apple-content-edited="true"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Everson Mono'; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Everson Mono'; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><br></div><div><span class="Apple-style-span" style="font-family: '-webkit-monospace'; ">Michael Everson * <a href="http://www.evertype.com/">http://www.evertype.com</a></span></div></div></span></div></span> </div><br></div></body></html>
