Ask for advice on exact requirements to fix #699 mixed CJK numbers

[outdream]

I have finished the test and push code to github.

The implementation is different with my plan in last email:
> I plan to fix the issue with adding cases to check_infix() and
check_infix_digit().
I gave up the thought as it wouldn't work for continuous Chinese characters.
And the final implemation was done with hard-code check for Chinese digits.

please review the code when you are convenient, thanks.

Cheers,
outdream
