Peter Teeson - 2020-07-13

The macOS IOKit.framework /headers/usb contains 4 headers. 3 of them are encoded with Latin 1 i.e. ISO-8859-1 and the other is encoded with UTF-8.

I run Doxygen on the project generating latex code but doing make gives this error:
! Package inputenc Error: Invalid UTF-8 byte "B5.

(This is the greek/math symbol mu( µ) used in the header documentation in the word µsecs)

The TeX mailing list advises me to use varios commands in the file preamble.and or content.
However these files are locked since they are System code.

My Question:
What do you suggest as the most elegant, general, and practical way to solve this issues.

TIA for your help

P.S. The project has several hundred files after pre-processing so I seek a generic approach in case this occurs elsewhere.
