Certain pwsafe passwords my cause Malformed UTF-8

[hartsjc]

clipsafe -f ~/XXXX.psafe3
File: ~/XXXX.psafe3
Enter password safe combination:
Malformed UTF-8 character: \x81 (unexpected continuation byte 0x81, with no preceding start byte) in pack at /usr/local/src/clipsafe/clipsafe line 239, line 1.

Malformed UTF-8 character (fatal) at clipsafe line 239, line 1.

While not robust testing, the following line 212 seems to resolve the issue for me.

211                 $plain .= $buf;
212                 utf8::encode($buf);
213                 #print unpack("H*", $buf), "\n";
