3071290 - "unsupported character" error during Document Generation step in SAP SuccessFactors Onboarding

• Example error traces (from Business Process Todo):
  • {"code": null, "message": "unsupported character! XXX}}"}
  • HCP Response Content: {"error":{"code":null,"message":"unsupported character!"}}

SAP Successfactors Onboarding

1. Generate onboarding documents (e.g., forms populated with candidate data).
2. Error is recorded in BPE with “unsupported character”.

Scenario A: Arabic language content

• Arabic text used in document generation is not supported by the Onboarding module’s document service.
• Result: Document generation fails with “unsupported character” errors in BPE.

Scenario B: Thai language content and font support

• Candidate data (e.g., first name/last name) mapped in Thai via Business Rules to a PDF form.
• Support for languages is tied to the fonts available in the document service.

Currently available fonts:

• • Commercial fonts: Arial, Times New Roman, Courier
  • Adobe open-source fonts:
    • SourceSerifPro-Regular (European languages such as English, French, German, etc.)
    • SourceHanSerifK-Regular (Korean)
    • SourceHanSerifSC-Regular (Simplified Chinese)
• If a form uses a font not among the above, or attempts to render a language with a font that does not support it, the service will overwrite to one of the listed open-source fonts for rendering.
• Thai is not supported by any of the listed commercial or included open-source fonts.

• Scenario A: Arabic language content

  • Arabic language is not currently supported within the Onboarding document generation module. Documents containing Arabic characters will not render successfully.
  • Recommendation: If Arabic is required for your business process, please submit an enhancement request.

• Scenario B: Thai language content and font support

  • Thai language is not supported by the currently available fonts in the document service (neither the three commercial fonts nor the included open-source fonts).
  • Recommendation:
    • Ensure forms use only the supported fonts listed above and languages supported by those fonts.
    • If Thai is required, please submit an enhancement request. This behavior is currently by design.
