Ship it!
Indeed there might be more places where this could be a problem.
If only KDE CI also had builds for ARM :)
Do you have commit rights to KDE repos? Otherwise I could commit for you.

> The C standard defines char to be either signed char or unsigned char. In this case, the char is used to store negative values to signify categories of characters as well as actual characters. Therefore it must be a signed char and doesn't work on platforms where char is unsigned (e.g. ARM). In this specific case, compilation of the file fails with:
