Summary of the Pull Request

This pull request addresses the handling of empty WordDelimiters lists to ensure stable and predictable behavior across all relevant functions.

References and Relevant Issues

N/A

Detailed Description of the Pull Request / Additional Comments

  • IsWordDelim function updates:

    • Added a condition to check if WordDelimiters is empty before proceeding with the standard logic.
    • Ensures that the function remains compatible with existing behavior while handling edge cases more effectively.

  • DelimiterClass function updates:

    • Similar logic applied to avoid unnecessary operations if WordDelimiters is empty.
    • Maintains compatibility and prevents errors related to uninitialized or empty delimiter lists.

These updates improve the stability of the codebase and align with best practices for handling potentially undefined states.

Validation Steps Performed

  • Verified the behavior of IsWordDelim and DelimiterClass with both empty and non-empty WordDelimiters.
  • Conducted manual testing to ensure there are no regressions or unexpected changes in functionality.

PR Checklist

  • Closes N/A
  • Tests added/passed: Verified functionality with both empty and non-empty WordDelimiters.
  • Documentation updated: No documentation updates required for this change.
  • Schema updated (if necessary): Not applicable.
