foomatic-rip crashes on titles with some special characters on Ricoh PS PPDs

Describe the bug
Job title TPS7A52 2-A, High-Accuracy (0.5%), Low-Noise (4.4 µVRMS), LDO Voltage Regulator datasheet (Rev. A) consistently crashes foomatic-rip filter.

To Reproduce
Steps to reproduce the behavior:

1. Open attached PDF, or generate your own with this title. TPS7A52 2-A, High-Accuracy (0.5%), Low-Noise (4.4 µVRMS), LDO Voltage Regulator datasheet (Rev. A).pdf

2. Print it to a foomatic-rip enabled PPD. In my case Ricoh MP C3004

3. See this error in the logs.

Expected behavior
It prints

System Information:

• OS: Debian Testing 13
• CUPS 2.4.12
• cups-filters: 1.28.17-5

Start by reproducing the crash with the attached PDF and Ricoh MP C3004 PPD, then inspect the foomatic-rip renderer command shown in the logs, especially the shell printf invocation. Done means the job completes without the invalid format character or broken-pipe errors and prints successfully.
