DOCX: bullet marker characters (lvlText) from numbering.xml ignored

[developer0hye]

Description

DOCX bullet lists always render with Typst's default markers (-) regardless of the custom bullet characters defined in numbering.xml. The lvlText values (e.g., ●, ○, ■) are not read or applied.

Root Cause

In crates/office2pdf/src/parser/docx.rs, build_num_kind_map() (line ~62) only determines whether a list is Ordered or Unordered by checking if the format is "bullet". The actual lvlText value that defines the marker character is never extracted.

The codegen (crates/office2pdf/src/render/typst_gen.rs line ~1197) then uses Typst's #list() for unordered lists, which renders with the default - marker.

numbering.xml example:

<w:abstractNum w:abstractNumId="1">
  <w:lvl w:ilvl="0">
    <w:numFmt w:val="bullet"/>
    <w:lvlText w:val="●"/>       <!-- filled circle -->
    <w:pPr><w:ind w:left="720" w:hanging="360"/></w:pPr>
  </w:lvl>
  <w:lvl w:ilvl="1">
    <w:numFmt w:val="bullet"/>
    <w:lvlText w:val="○"/>       <!-- open circle -->
    <w:pPr><w:ind w:left="1440" w:hanging="360"/></w:pPr>
  </w:lvl>
  <w:lvl w:ilvl="2">
    <w:numFmt w:val="bullet"/>
    <w:lvlText w:val="■"/>       <!-- filled square -->
    <w:pPr><w:ind w:left="2160" w:hanging="360"/></w:pPr>
  </w:lvl>
</w:abstractNum>

Expected

• Level 0: ● Item text
• Level 1: ○ Sub-item text
• Level 2: ■ Sub-sub-item text

Actual

All levels render with -:

• - Item text
  • - Sub-item text
    • - Sub-sub-item text

Fix Suggestion

1. Extract lvlText from numbering definitions and store per-level marker info
2. Extend the IR List or ListItem to carry custom marker characters
3. In Typst codegen, use #list(marker: [●]) or #set list(marker: [●]) to override default markers
