the Unrecognized switch: -O is from the perl call:

++ perl -CO -e 'print pack("U",0x00E4)'
Unrecognized switch: -O  (-h will show valid options).
+ auml=
++ perl -CO -e 'print pack("U",0x0061).pack("U",0x0308)'
Unrecognized switch: -O  (-h will show valid options).
+ aumlcdiar=

here is the output log:
