micromark Symbol Utilities

micromark-util-symbol is a core utility package within the unified collective's `micromark` ecosystem, specifically designed to provide a consistent set of constants. These constants include character codes, common character values, internal token types, and general numeric constants, all crucial for developers building extensions for `micromark`. As of version 2.0.1, the package maintains compatibility with Node.js 16+ and `micromark@3`. While individual utility packages within `micromark` don't adhere to a strict, predictable release cadence, the broader `micromark` project sees regular updates. This package's key differentiator is its provision of named constants that `micromark-build` compiles away for production, encouraging safer, more readable development code without incurring runtime overhead in optimized builds.
