kuromoji_readingform token filter
editkuromoji_readingform token filter
editThe kuromoji_readingform token filter replaces the token with its reading
form in either katakana or romaji. It accepts the following setting:
-
use_romaji -
Whether romaji reading form should be output instead of katakana. Defaults to
false.
When using the pre-defined kuromoji_readingform filter, use_romaji is set
to true. The default when defining a custom kuromoji_readingform, however,
is false. The only reason to use the custom form is if you need the
katakana reading form:
