Hi,
(This e-mail is because we have a bug about a camera name which seems
not to be in utf-8,

I was told
(http://www.mail-archive.com/linux-uvc-devel@xxxxxxxxxxxxxxxx/msg04022.html)
that camera names (and possibly others, such as device names) are
recorded as utf-16 in cameras, and linux usb subsystem transforms them
to latin-1 (iso-8859-1) before making them available to applications.
This is an inconvenient for applications which should print them (to
terminal or to windows), as nowadays utf-8 is ubiquitous.
So my question is: why does usb linux use latin-1 and not utf-8?
Because the code was written that way originally and nobody has ever
changed it. This may sound facetious, but it is the simple truth.
Thanks for the fast reply!
I see now the corresponding function, at
http://lxr.linux.no/linux+v2.6.29/drivers/usb/core/message.c#L761. I
looked at several places where it is used, and until now it seems that
changing it to utf-8 has no negative impacts on the other code. Do you
think that it is feasible (easy) to really make this change?
