[ID-4258070]Disappearing Punctuation Marks in Hebrew RTL Justified Text in Exported PDF

Severity Level: Critical
Impact: Severe disruption to Hebrew text layout workflow and document integrity

Bug Description

Punctuation marks are randomly disappearing in justified Hebrew text blocks (RTL direction), specifically at:
- Paragraph endings
- Forced line breaks
- Last lines of justified paragraphs

Technical Context

  • Text Direction: Right-to-Left (RTL)
  • Language: Hebrew
  • Text Alignment: Justified

Affected Punctuation Marks

  • Periods (.)
  • Semicolons (;)
  • Commas (,)
  • Colons (:)

Specific Behavior in RTL Context

  1. When Hebrew text is set to justified alignment, punctuation marks vanish:
    • At the end of paragraphs
    • Before forced line breaks
  2. Exception: Punctuation marks remain visible if the last line is explicitly right-aligned
  3. The issue appears to be specific to RTL text direction and does not occur in LTR text

Known Workarounds and Their Limitations

  1. Legacy Composition Engine Option:

    • While switching to the legacy composition engine in preferences resolves this specific issue
    • We strongly advise against this solution due to:
      • Previously reported bugs and limitations in the legacy engine (see bug reports #ID-4245219)
      • Performance issues documented in our earlier reports
      • Compatibility concerns with newer features
    • We require a proper fix in the current composition engine rather than reverting to legacy solutions

  2. Temporary Layout Workaround:

    • Right-align the last line of affected paragraphs
    • This is not viable for production as it:
      • Affects layout consistency
      • Requires constant manual intervention
      • Disrupts automated workflows

Technical Impact

  • Compromises Hebrew document accuracy
  • Requires constant manual checking and fixes
  • Disrupts automated workflows for Hebrew text processing
  • May lead to incorrect final output in published Hebrew materials

Priority Level

Immediate attention required as this bug:
- Affects core Hebrew typography functionality
- Creates significant quality control issues in RTL text layouts
- Requires time-consuming manual verification
- May result in incorrect published content

Steps to Reproduce

  1. Set paragraph direction to RTL
  2. Create a Hebrew text block with justified alignment
  3. Type a paragraph ending with any punctuation mark
  4. Add forced line breaks within the paragraph
  5. Observe the disappearance of punctuation marks at:
    • Paragraph endings
    • Before forced line breaks

Technical Investigation Request

Please investigate:
- RTL text rendering engine behavior
- Interaction between justified alignment and RTL text direction
- Potential conflicts between Hebrew text processing and punctuation handling
- Implementation of punctuation handling in the current composition engine

Request

Immediate investigation and hotfix needed in the current composition engine. While we acknowledge the existence of a legacy engine workaround, we require a proper fix in the current engine to maintain workflow efficiency and compatibility with modern features.
