Re: Processing Digit Variants

There might be reasons to extend number parsing to support digits with
variation selectors.

However, the status quo in ICU is that variation selectors terminate
numbers in both number parsing (DecimalFormat class) and in numeric
collation (Collator).

Numeric collation is actually much more limited than number parsing, to
strictly strings of digits, not including sign (thus only non-negative),
decimal, exponent, etc. More processing in the bowels of the collation code
would be very complicated, and ambiguous: "file-5.txt" is probably file
number 5 rather than file minus five.
