Changes in version 0.1.3 (2026-05-21)                  

  - Fixed an installation failure on some Linux platforms caused by
    internal lookup environments using Chinese characters as object
    names. The environments now use ASCII-only Unicode code-point
    strings (e.g. "13312" instead of "㐀"), which avoids Error in
    envlist(e) : object '㐀' not found during lazy-load database
    creation.

                        Changes in version 0.1.2                        

  - New to_pinyin_marks() returns Pinyin with diacritic tone marks (e.g.
    qiū) directly from the Unicode Unihan kMandarin field, correctly
    handling the neutral tone (tone 5) where the source data marks it.

                 Changes in version 0.1.1 (2026-04-22)                  

  - Added citation to Unicode Unihan Database in DESCRIPTION.
  - Added missing \value tags to Rd documentation.

                        Changes in version 0.1.0                        

  - Initial CRAN release.
  - Vectorized conversion of Chinese characters to Hanyu Pinyin.
  - Dictionary sourced from the Unicode Unihan Database (kMandarin).
  - Support for tones, toneless output, initials, URL slugs, and valid R
    variable names.
  - Built-in phrase table for common polyphones with user-extensible
    overrides.
