How does it handle invalid UTF-8 sequences?

It follows a deterministic policy: it consumes at least one byte, returns the replacement character U+FFFD, and marks the result as invalid for the caller.

Does this skill require specific system headers?

No, it enforces an OS-header-free requirement, ensuring the Unicode logic remains portable and contained within the project's utility directories.

How are emojis handled in terms of display width?

The skill implements an emoji-wide policy, where emoji characters are consistently measured as occupying 2 terminal columns.

Can this skill help with text wrapping?

Yes, it provides logic for deterministic wrapping primitives that respect grapheme boundaries and column width policies.

What Unicode version does this skill support?

The skill is pinned to Unicode version 15.1.0 to ensure deterministic behavior and consistency across all implementations.

Implements deterministic UTF-8 decoding, grapheme segmentation, and terminal width policies for robust TUI development in C.

The zireael-unicode-text skill provides Claude with the specialized domain knowledge required to maintain the Zireael TUI engine's core text processing logic. It enforces strict adherence to Unicode 15.1.0 standards, ensuring that text rendering, wrapping, and measurement remain deterministic across different environments. This skill is particularly useful for developers building low-level terminal interfaces where precise character alignment, emoji width handling, and resilient UTF-8 error recovery are mandatory for visual consistency and stability.
