Replace the private Encode::_utf8_on() with utf8::decode() and Encode::is_utf8() with utf8::is_utf8(). Both are core Perl functions available since 5.8 — no module import needed. utf8::decode() is superior to _utf8_on(): it validates the byte sequence as legal UTF-8 before setting the flag, whereas _utf8_on() blindly flips the flag even on invalid bytes. This removes Encode from runtime prerequisites entirely (dist.ini, cpanfile, Makefile.PL), making the dependency tree lighter. Supersedes #10. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

What
Replace
Encode::_utf8_on()+Encode::is_utf8()with coreutf8::decode()+utf8::is_utf8(), removing theEncodemodule from runtime dependencies entirely.Why
Encode::_utf8_on()is a private API (leading underscore = not for public use). It blindly sets the UTF-8 flag without validating the byte sequence.utf8::decode()is a core Perl function (since 5.8, no import needed) that validates the bytes are legal UTF-8 before setting the flag — strictly better behavior.This also makes the module lighter: one fewer runtime dependency.
Supersedes #10 which replaced
_utf8_onwithutf8::upgrade— butupgradeis wrong here (it re-encodes Latin-1 → UTF-8, causing double-encoding of already-UTF-8 bytes).utf8::decodeis the correct replacement.How
Encode::_utf8_on($s)→utf8::decode($s)(validates + sets flag)Encode::is_utf8($s)→utf8::is_utf8($s)(core equivalent)use Encode ()from WebHook.pmEncodefrom dist.ini, cpanfile, Makefile.PL prerequisitesuse Slack::WebHookinexamples/start-end.plTesting
