> Found this while writing up the solr ref guide for DecimalDigitFilter.
> With input like "𝟙𝟡𝟠𝟜" ("Double Struck" 1984) the filter produces "1𝟡8𝟜" (1, double struck 9, 8, double struck 4) add some non-decimal characters in between the digits (ie: "𝟙x𝟡x𝟠x𝟜") and you get the expected output ("1x9x8x4"). This doesn't affect all decimal characters though, as evident by the existing test cases.
> Perhaps this is an off by one bug in the "if the original was supplementary, shrink the string" code path?
