@lnxw48a1 @bobjonkman When I write about different currencies, I never use the strange $nnn format, much less e.g. HK$nnn, it never made sense to me.
Keep it as a local convention when it's obvious which $, fine, same with "nnn kr" for Swedish crowns, but in international comparisons, I wish everyone could treat currencies as normal units and use the international symbols, like 100 USD = 780 HKD = 100 EUR = 1000 SEK, instead of US$100 = HK$780 = 100 EUR = 1000 kr.
