Pull request overview
This PR fixes the AWS SigV4 signature calculation to correctly handle multi-byte UTF-8 characters in URI paths. The issue was that the code was encoding the entire UTF-8 byte sequence as a single unit, when each byte should be percent-encoded individually.
Key changes:
- Modified the loop in
escapeURIPathto iterate over each byte of the encoded UTF-8 rune individually - Simplified
encodeHexUpperto accept a single byte instead of a byte slice, removing the internal loop
