strj_fill_iter_mark: Fill Japanese iteration marks

In audubon: Japanese Text Processing Tools

Fill Japanese iteration marks

Description

Replaces Japanese iteration marks in character strings with the corresponding repeated characters.

This function scans each input string and expands iteration marks such as odoriji by inferring the characters to be repeated from the surrounding context. The implementation is heuristic and intended for practical text normalization rather than complete linguistic accuracy.

Usage

strj_fill_iter_mark(text)

Arguments

text	A character vector containing Japanese text.

Details

The restoration is based on local character context and may be incomplete for iteration marks that refer to longer or more complex spans.

Value

A character vector in which iteration marks are replaced with the inferred repeated characters.

Examples

strj_fill_iter_mark(c(
  "\u3042\u3044\u3046\u309d\u3003\u304b\u304d",
  "\u91d1\u5b50\u307f\u3059\u309e",
  "\u306e\u305f\u308a\u3033\u3035\u304b\u306a",
  "\u3057\u308d\uff0f\u2033\uff3c\u3068\u3057\u305f"
))
