I can only speculate as long as you don't show us a Dump of $str.

I think if the encoding of the output channel is byte oriented, this would explain your false negative results.

IOW your decoding is right but the test is wrong.

update

Yep, tested on my Ubuntu VM, with utf8 console

DB<2> use Devel::Peek DB<4> use Encode qw(decode encode) DB<10> $str="k" DB<11> Dump $str SV = PV(0x28054a0) at 0x280a370 REFCNT = 1 FLAGS = (POK,pPOK) PV = 0x2838a60 "k\303\274"\0 # <-- 303 274 is octa +l for UTF-8 encoding of "" * CUR = 3 LEN = 16 DB<12> p $str k DB<13> p $dec = decode("utf8",$str,Encode::FB_WARN) k DB<14> Dump $dec SV = PVMG(0x28e41f0) at 0x2a19368 REFCNT = 1 FLAGS = (POK,pPOK,UTF8) IV = 0 NV = 0 PV = 0x28fe5a0 "k\303\274"\0 [UTF8 "k\x{fc}"] # <-- correct UTF8 U+ +00FC is codepoint for "" CUR = 3 LEN = 16 DB<15> binmode DB::OUT,':utf8'; # <-- fix encoding la +yer DB<16> p $dec k DB<17>

DB<19> printf "%X ", $_ for  0303, 0274

DB<20> printf "%X ", oct($_) for  qw/303 274/
