Bug Description

When an experience entry's position field contains Markdown italic markers (*...*), the generated Typst file has garbled #emph[/] brackets, causing the Typst compiler to fail with:

TypstError: missing argument: date-and-location-column

Steps to Reproduce

Use the sb2nov theme (or any theme with a similar template) and create an experience entry where the position field contains multiple italic spans:

cv:
  name: John Doe
  sections:
    experience:
      - company: Freelancing consultant by **Acme Corp**
        position: Worked in resort *ProjectAlpha* and also on project *ProjectBeta*
        start_date: 2020-01
        end_date: 2021-01
        highlights:
          - Did some work

Then run:

rendercv render cv.yaml

Root Cause

The experience entry template for main_column is:

**POSITION**
*COMPANY*
SUMMARY
HIGHLIGHTS

After placeholder substitution, this becomes (for the example above):

**Worked in resort *ProjectAlpha* and also on project *ProjectBeta***
*Freelancing consultant by **Acme Corp***

These two lines are separated by a single \n, which means Python's markdown library treats them as one paragraph. The */** emphasis markers from the POSITION line interact with the * on the COMPANY line, and the parser misresolves the overlapping emphasis boundaries.

This produces garbled Typst output like:

#strong[Worked in resort #emph[ProjectAlpha#emph[ and also on project ]ProjectBeta#emph[)]#emph[
]Freelancing consultant by ...]]

instead of the correct:

#strong[Worked in resort #emph[ProjectAlpha] and also on project #emph[ProjectBeta]]
#emph[Freelancing consultant by ]#emph[Acme Corp]

The mismatched [/] brackets corrupt the #regular-entry() function call syntax, which is why Typst reports missing argument: date-and-location-column.

Proof

from rendercv.renderer.templater.markdown_parser import markdown_to_typst

# Single line — works fine:
markdown_to_typst('**Worked in resort *ProjectAlpha* and on *ProjectBeta***')
# → #strong[Worked in resort #emph[ProjectAlpha] and on #emph[ProjectBeta]]  ✓

# Multi-line as produced by template — broken:
markdown_to_typst('**Worked in resort *ProjectAlpha* and on *ProjectBeta***\n*Freelancing consultant by **Acme Corp***')
# → garbled output with mismatched brackets  ✗

Impact

• Any entry whose position (or other first-row field) contains multiple Markdown italic spans will trigger this.
• It appears content-length-dependent because longer CVs are more likely to contain such entries, but it's purely a content pattern issue.
• Affects v2.6 and v2.7 (current main). v2.3 was not affected.

Suggested Fix

Either:

1. Separate template lines with \n\n so Markdown treats them as independent paragraphs, or
2. Apply markdown_to_typst() to each line independently before joining them into the multi-line field.

Environment

• rendercv v2.7 (also v2.6)
• Python 3.12
• macOS
