There is huge potential for some really interesting and challenging
Unicode exercises. If you have any suggestions for such exercises they
would be most welcome. Email me direct or share on this list.
A simple challenge is to write a function which localize numbers in a
script having decimal digits or parse them (i.e. which have characters
with property Numeric_Type=Decimal, as explained in §4.6 of the Unicode
10 standard). The list of these scripts is specified in table 22-3.
There is usually a most one set of digits/script (with the exception of
Arabic, Myanmar and Tai Tham).
Then, of course, one can look at other numeral systems (CJK, Ethiopic,
Roman, to name a few in contemporaneous use). The section 22.3 of the
Unicode standard is an interesting starting point for these.
A internationalised exercise which doesn’t (always) use unicode is the
localization of separators in numbers: 2¹⁰+π = 1,027.14 in US and 1
027,14 in France. One also should not forget that half a million is
5,00,000 in India. These simple things can be very surprising the first
time you meet them.
