Description

The covers: regex(...) functionality for font selection appears to have regressed in v0.14.0. A regex designed to match a specific Unicode range (e.g., [\u2780-\u2789] for Circled Sans-Serif Digits) no longer selects the specified font.

This exact code worked as expected in v0.13.1, correctly applying "Noto Sans" to the special character.

For other cases like a number matching ([0-9]) it works as expected.

Minimal Example

#set text(lang: "de", font: ((name: "Noto Sans", covers: regex("[\u2780-\u2789]")), "Georgia"))

Actual: Hello ➁

Desired: Hello #text(font: "Noto Sans")[➁]

➁ \u{2781}

Actual Behavior (v0.14.0)

The Actual: line renders the ➁ character using the font ("Georgia"), not "Noto Sans". The covers: regex(...) condition is seemingly ignored or fails to match.

Expected Behavior (v0.13.1)

The Actual: line should render the ➁ character using the "Noto Sans" font, as it matches the Unicode range in the regex. The output of the Actual: line should be identical to the output of the Desired: line.
