"If it can be verified": and that's the point. I'm not talking about how to be more neutral. We can't verify some ancient characters or writing system easily, even those not to be used these days. In the case of Mesopotamia, it sounds unrealistic to use cuneiforms in OHM. Alphabetic writing is dominant in many history books about that area, because it's more practical, of course. Mexian civilizations (Maya, Aztec) are in similar situation, too. You can see the name of the capital of Aztec Empire on OHM now - Tenochititlan.
In OHM, the place names in Hong Kong are written in alphabets and Chinese characters, even before the occupation by the UK. I guess that's not a mistake, and it's useful for Hong Kong people who use the both characters. There's another example. Tibet region has their own characters that had been widely used, but it seems to be written in Chinese characters only. How about the Mongolian scripts in Yuan dynasty, and the Manchu scripts in Qing dynasty? All of them would be written only in Chinese characters, and it is. Chinese users needs them to verify those place names.
I understand your opinion and would like to write Hanja. But not only. Korean users need Hangul to verify the old place names as ever.

There's an mistake on the last comment: "of the occupition by the UK and Portugal, respectly". I'm thankful for your interests and contributions about the Korean peninsula, as so I have been doing that. But now, this is the problem that need to consider how it is helpful for OHM users, as I think.

I surely understand the historical background of that, but the OHM is the service for users of the present time. I think it should to be more interpretable so it couldn't make any obstacle to understand the map. It doesn't have to use sort of cuneiform for writing city names of the Mesopotamian civilization. Also, despite the history of the occupition by the UK, not used only alphabets for place names in Hong Kong / Macau, China. Now, Same as here.

Please stop writing Korean city names by the chinese characters on the Name parameter. We don't write like that and can't read it.
