Sort code points with an explicit English collation.

Canonical: https://1loc.dev/string/sort-the-characters-of-a-string-in-the-alphabetical-order/
Version: 1.0.0
Runtime: JavaScript · Node.js 22 / modern browsers
Verification: Local fixtures; no external services
Updated: 2026-10-28

## Implementation

```javascript
function sortCharacters(text) { return Array.from(text).sort((a, b) => a.localeCompare(b, 'en')).join(''); }
```

## Input

```json
"hello"
```

## Expected output

```json
"ehllo"
```

## Edge case

Input:
```json
"Bab"
```
Output:
```json
"abB"
```

## Limits

- The original used the runtime’s default locale, which can differ between machines; this version names the locale.

The lab validates types and size before calling this function. Add equivalent validation at your own trust boundary.
