I don't think there will be a standardized list of all the place names. mi pilin e ni: jan mute li kama sona e toki pona la nasin jan en nasin kalama li ken ante.
What may be interesting to see is how each country's speaker would tokiponize their own stuff. I know jan Sonja called my country ma Malasija in lipu pu, but I would naturally sound more as ma Malesija, and I know that jan poka mi li pilin sama.
ma Mosijo for Hungary is objectively terrible as far as transliterations go, though I quote like that it's one of the very few if not only that changed very early on (2005 iirc -- it was Masija, which was too similar to Asija).
The 'gy' /ɟ~ɟ͡ʝ/ in magyar* becoming an /s/ is just weird, though can be reasoned (/ɟ~ɟ͡ʝ/ > /dʲ/ > /di/ > /ti/ >** /si/ -- the semivowel then added back), it's still one syllable too long. 'a' is an /ɒ/ in Hungarian, that becoming an 'o' is arguably acceptable (although I'd argue against it, but given the circumstances, I won't complain).
Better solution? "Mata" for Hungarian could work I guess, all I know is that U'd greatly orefer having a plosive in it than a fricative.
*: the country's name is Magyarország, where magyar=Hungarian, ország=country **: by toki pona syllable rules
In pu the dictionary, place names (and a few other parts) are under CC-BY-NC, so they can be shared as they appear, but I don't know any place that has them. I used to read jan Pije's copy of it on http://tokipona.net/tp/janpije/placenames.php, but it too have been taken down sadly. The link is for an archived version.
Others can maybe give better sources, I am not sure what's up to date and accurate.
My thanks!
