The boiler-plate header section of the .h files in the STM32 section of CMSIS have a stray non-standard ISO character the messes up standard unix / linux system tools, eg. grep , sed , etc.
This seems to be automatically reproduced in each file so this character is identically present in line 12 of every file in the CMSIS/ST/STM32F4xx directory.
It is the apostrophe in ''peripheral's''. This odd character is causing a false end of line for sed and causing grep to see these files as ''binary'' and not display text matches.
A test case is to try to find occurrences of a defined constant using grep:
grep -R SPI_CR2_DS_2 .
The .h files are reported as being binary and search results are not displayed.
Expected result: the code base should use standard ISO characters accessible on all platforms.
