RTL languages are encoded logically, just like LTR languages. What
appears *first* is first, not what appears to the *left*. Numbers are
always LTR. I don't think there's any issue wrt bidi.

Numbers in other languages could be an issue. I don't expect to see
e.g. Chinese numbers in a progress meter or gauge--they use Western-style
digits for calculations and such--but I wouldn't be surprised to see Arabic
use its own numbering system.

Another i18n issue is commas vs. periods as the decimal point.

A typographical issue is the use of punctuation or spaces as the thousands
separator.

Another issue is the possible use of U+2212 MINUS SIGN intead of U+002D
HYPHEN-MINUS. This last, at least, should be handled whenever the number
is parsed from the text content rather than in an attribute.
