Thanks for the updated patch. Applied here:
https://git.gnome.org/browse/libxml2/commit/?id=0b19f236a263a7b0acacd4ea84dc7237303ee3d9
The original bug found by fuzzer only relates to UTF8 decoding, so using
Shift-JIS or anything else wont help.
Why not? My reasoning was that ICU uses the same code path for all
variable-width encodings. I simply converted your test file to EUC-JP and it
turns out that this triggers the bug as well:
