From what I know, depending on the country you live, there are different ways of expressing a date range between two dates.
In Japanese :
0000/00/00 ~ 0000/00/00
0000/00/00 から 0000/00/00 まで
0000/00/00 -> 0000/00/00
From 0000/00/00 to 0000/00/00
0000/00/00 - 0000/00/00
Du 0000/00/00 au 0000/00/00
Now the problem is that I would like to use a single convention that can be easily understood in any culture.
Maybe I'm over-thinking it but the "->" symbol might be interpreted as a transformation instead of a range. I'm also afraid that the "~" might not be understood everywhere the same way (http://en.wikipedia.org/wiki/Tilde).
So, what single symbol would you use for a globalized UI?
