Hi Christian,

That's what I am thinking. I think TokenFilter would be a good choice to implement that feature.
We can use POS tag to recognize what a token is. We can apply normalization if a token is
a numeral prefix/suffix with numerals.

> 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).
