Following Dato's suggestion to add more commonly seen Arabic "words" (not sure if that is the correct term TBH!) to the special keyboard, I have taken the liberty of starting a similar suggestion for the Chinese/Japanese special keyboard.
This is what is currently available:
Essentially numbers 0-9, and common names for China, PRC and Republic, as well as Japan and Hong Kong and a few other ideograms.
I suggest we add these, commonly seen on coinage:
通寶 (Tong Bao); these characters are recurring on almost all Chinese, Vietnamese, etc. cash coins from the Song dynasty onwards.
大清 (Dai Qing/Great Qing); for machine struck coins of the Qing dynasty 1889-1911;
The names of countries where Chinese is a language regularly used on coins; currently exists for the PRC, Taiwan, Hong Kong and Japan; but Singapore (新加坡) and Macau (澳門) could use this too.
The regnal names of Chinese and Japanese emperors, at least from the Qing for the former and since Meiji for the latter; we already have the second except Meiji (明治).
Any further suggestions are welcome!
