Hi,
I'm making some rust bindings for alsa-lib [1] and Rust is quite picky about strings; i e, requires them to be UTF-8.
1a) can I count on alsa-lib's strings (everything from card name and mixer identifiers to various descriptions) to be UTF-8 or perhaps even 7-bit? If not, what encoding is to be expected?
1b) In what way can buggy drivers violate the answers to 1a?
2) Can I count on the strings to be zero terminated? E g, I looked at snd_ctl_elem_id_set_name http://www.alsa-project.org/alsa-doc/alsa-lib/group___control.html#ga813d02a44a9d01a4a2fe81eda7a8670a that sets all 44 characters without ensuring a zero at the last character, but snd_ctl_elem_id_get_name http://www.alsa-project.org/alsa-doc/alsa-lib/group___control.html#gaa6cfea3ac963bfdaeb8189e03e927a76 does not say anything about a max length, it just gives out a *const char. The question applies to all other strings as well.
