Research method
Unicode Text Compatibility Method
This versioned 12-style by 5-environment matrix publishes the current recorded outcome and evidence status for each cell. Untested cells remain explicit.
Evidence status
0 of 60 cells contain recorded results
Catalog revision catalog-v1-default-cldr-48-2-40-styles records 0 tested outcomes and 0 evidence attachments. Untested cells remain explicitly marked, and this research page remains noindex while review is incomplete.

Method before conclusions
A valid result must record the exact device, operating system, app or browser version, input field, test date, fixture, outcome, and evidence path.
No percentage or platform claim is calculated while the matrix remains untested. A visible glyph alone would not establish copying, saving, searching, or assistive-technology behavior.
Current limitations
The rows represent style mechanisms, not every output in the 40-style registry. The five environments are a planned sample, not universal coverage.
A published preview subset may load through versioned CSS, but that visual resource is not compatibility evidence for the destination. Copied output remains Unicode text, and user input stays memory-only and never enters the preview request.
Each published revision reports only its recorded cells; untested cells remain explicit, and this research page stays noindex while review is incomplete.
