Unfortunately, we do not have any experience on ARM, all mobile apps uses LibRaw on own risk, we're unable to provide any support for this (no development toolchain, no emulators, nothing).
If you're able to get real file samples that produces repeatable problem (and the problem is reproducible on PC/Mac), please share samples with us (info@libraw.org). Without samples it is very hard to say anything.
We have some (limited) sales of our FastRawViewer (uses LibRaw, of course) to Chinese users and there is no chinese-specific bug reports.
