Use Case

As a javascript engineer
I want to improve the performance of parsing <20 byte basic latin strings in BSON
So that BSON keys and short string values decode faster

User Impact

• Basic Latin strings should decode faster than before this change

Dependencies

• None

Unknowns

• None

Acceptance Criteria

Implementation Requirements

• Use String.fromCharCode if bytes are between [0, 127] and sequences are less than 20 bytes
• Refactor UTF8 validation to occur iff bytes exceed the above range

Testing Requirements

• Run benchmarks
• Ensure byte sequences that contain a byte greater than 127 still operate

Documentation Requirements

• None

Follow Up Requirements

• None
