Is it difficult to support numbers with period as the following?
3.2兆円
5.2億円
{quote}

Supporting this is no problem and a good idea.

I think It would be helpful that this charfilter supports old Kanji numeric characters ("KYU-KANJI"
or "DAIJI") such as 壱, 壹 (One), 弌, 弐, 貳 (Two), 弍, 参,參 (Three), or configureable.

This is also easy to support.

As for making preserving zeros configurable, that's also possible, of course.

It's great to get more feedback on what sort of functionality we need and what should be configurable
options. Hopefully, we can find a good balance without adding too much complexity.

Thanks for the feedback.

> Japanese people use Kanji numerals instead of Arabic numerals for writing price, address
and so on. i.e 12万4800円(124,800JPY), 二番町三ノ二(3-2 Nibancho) and 十二月(December).
 So, we would like to normalize those Kanji numerals to Arabic numerals (I don't think we
need to have a capability to normalize to Kanji numerals).
