Some searches error

[coke]

While search works in general:

➜  uni git:(master) raku -I. bin/uni -n stuff
🥙 - U+01F959 - STUFFED FLATBREAD [So]

Some search strings cause... problems:

➜  uni git:(master) raku -I. bin/uni -n dead
Error encoding UTF-8 string: could not encode Unicode Surrogate codepoint 57005 (0xDEAD)

(note the error is on DABC, not ABC)

but it's not every matching possible hex string:
