Why am I receiving a font error when logging into the Oracle B2C Service console?

Environment:

Agent Login, Oracle B2C Service console, All versions

Resolution:

This error indicates a problem with a specific Windows font pack. While the specific <font> or <style> indicated in the error message can vary, the existence of this error can be caused by (but not limited to) the following:

- A missing or corrupted Windows font or specific style of font. Check to make sure that the specified font and style are present in the Windows 'Fonts' menu located in the Control Panel. Reinstall font if necessary.

- A corrupt installation of Microsoft .NET Framework. Check your version of Oracle Service system requirements and reinstall the .NET Framework as necessary.

- A missing or corrupted Windows system file or Windows installation. Some bad files can be identified and corrected using Microsoft's System File Checker utility. If no other steps are successful in correcting the issue a full reinstall of the operating system may be necessary.
