In quarto: R Interface to 'Quarto' Markdown Publishing System

YAML character handler for YAML 1.1 to 1.2 compatibility

Description

This handler bridges the gap between R's yaml package (YAML 1.1) and js-yaml (YAML 1.2) by quoting strings with leading zeros that would be misinterpreted as octal numbers.

Usage

yaml_character_handler(x)

Arguments

x	A character vector

Details

According to YAML 1.1 spec, octal integers are ⁠0o[0-7]+⁠. The R yaml package only quotes valid octals (containing only digits 0-7), but js-yaml attempts to parse ANY leading zero string as octal, causing data corruption for invalid octals like "029" → 29.

Value

The input with quoted attributes applied where needed
