UTF-8 Round-Trip Test

Demonstrates UTF-8 handling across all PAGI input vectors.

Run

pagi-server --app examples/12-utf8/app.pl --port 5000

Visit http://localhost:5000/

Tests

1. Path Test - /echo/{utf8_string}: $scope->{path} is decoded, $scope->{raw_path} is bytes
2. Query String Test - ?text={utf8_string}: Percent-encoded bytes
3. POST Body Test - Form submission: Application decodes percent-encoded body
4. Response Test - UTF-8 literals encoded for wire, Content-Length in bytes

Key Points

• $scope->{path} is already UTF-8 decoded
• Query strings and bodies arrive as bytes - app must decode
• Response bodies must be encode_utf8() before sending
• Content-Length must be byte length, not character count
