These outputs are Unicode characters or combining marks, not downloadable font files. Coverage and appearance vary by app, font, language, and operating system; unsupported characters are intentionally preserved. Styled Unicode may also affect search, accessibility, or screen-reader pronunciation, so keep ordinary text for critical content.

Fancy text portability cluster

Style once, then check whether the destination can carry it

Unicode styling can increase code points, UTF-16 units and UTF-8 bytes even when the text looks the same length. Compare the current output against the destination's real limit, then keep a normalization or plain-text fallback ready.

Bold-looking Unicode is different from formatting

The generated characters are separate Unicode symbols, not a CSS or word-processor bold style. They can survive copy/paste where styling would be removed, but compatibility and accessibility are less predictable. Use real formatting when the destination supports it and the text needs semantic emphasis.

Unicode styling with explicit coverage and fallback

The transformation preserves unsupported characters, reports grapheme/code-point/byte differences, and flags compatibility-normalization changes instead of implying that every script has a matching styled alphabet.
