Function normalizeUnicode

normalizeUnicode(val: string): string
Normalizes a Unicode string according to the application's configured normalization form.

Unicode normalization ensures text consistency by converting characters to a canonical representation. This is crucial for text comparison, searching, and data integrity, as the same visual text can be represented differently in Unicode (e.g., é as a single character vs. e + combining accent).

The normalization form is configured via psy.set('unicodeNormalization', form) in app/conf.ts. The default form is 'NFC'. All strings and string arrays passed into Dream models are automatically normalized before database storage (values in JSON/JSONB fields are not automatically normalized). String values in queries (e.g., where, and) are automatically normalized to ensure search consistency.
Parameters
- val: string
  The string to normalize
Returns string
The normalized string, or the original string if normalization is disabled ('none')
See
- Unicode Normalization Forms (UAX #15)
- String.prototype.normalize()
Example
```
// With NFC normalization (default)
normalizeUnicode('café') // Returns normalized form of café

// With normalization disabled
psy.set('unicodeNormalization', 'none')
normalizeUnicode('café') // Returns original string unchanged
```
