Garbled Chinese characters in Effects feature Presets dropdown menu

### Bug description

In the Effects feature module（Compressor, Limiter, Reverb, Bass and Treble ）, Chinese text inside the dropdown menu fails to render correctly, displaying as garbled characters (e.g., – or 锟斤拷). This impairs user recognition an

d interaction.

### Steps to reproduce

1. Click the button “Effects“
2. Click the button “Add effect“
3. Select an effect (Compressor, Limiter, Reverb, Bass and Treble )
4. Preset dropdown menu Chinese random code

### Expected behavior

All Chinese text appears as mojibake (garbled characters), including question marks, diamonds, or non‑ASCII symbols.

### Actual behavior

Chinese characters in the dropdown should be displayed clearly as readable Simplified/Traditional Chinese, with proper encoding and legible font.

### Audacity Version

Audacity 4.0.0

### Operating system

Windows

### Additional context

Windows 11
Installation Pack：audacity-win-4.0.0-x86_64.msi
Software Preference：Appearance Font face：Microsoft YaHei UI

Start by reproducing the issue in the Effects feature's Compressor, Limiter, Reverb, and Bass and Treble preset dropdowns on Windows 11 with Microsoft YaHei UI selected. Trace the preset text and encoding used by those dropdowns, then verify that all Chinese entries render as readable Simplified or Traditional Chinese in the Audacity 4.0.0 installation scenario.
