hanyupinyin 0.1.3

• 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.

hanyupinyin 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.

hanyupinyin 0.1.1

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

hanyupinyin 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.
