International Blog URL Generator

Build a system that generates URL-friendly slugs for blog post titles in multiple languages, ensuring proper locale-specific character transliteration.

Requirements

You need to implement a blog URL generator that:

1. Takes blog post titles in various languages and converts them into URL-safe slugs
2. Applies locale-specific transliteration rules based on the content's language
3. Handles Swedish, German, and Turkish content with appropriate locale settings
4. Provides consistent slug generation across the application

Locale-Specific Requirements

Your implementation must handle these specific cases:

• Swedish content: Swedish characters (å, ä, ö) should follow Swedish transliteration conventions
• German content: German umlauts (ä, ö, ü) and ß should follow German transliteration rules
• Turkish content: Turkish-specific characters (İ, ı, Ş, ş, Ç, ç, Ğ, ğ) should be transliterated according to Turkish conventions
• Mixed/Default content: Content without a specific locale should use default transliteration

Function Signatures

Implement a module that exports:

1. A function generateSlug(title: string, locale?: string): string that generates a slug with optional locale
2. A function generateLocalizedSlugs(posts: Array<{title: string, language: string}>): Array<{title: string, slug: string}> that processes multiple posts with their respective locales

Test Cases

• Given the Swedish title "Räksmörgås och öl", with locale 'sv', returns 'raksmorgas-och-ol' @test
• Given the German title "Föhn und Größe", with locale 'de', returns 'foehn-und-groesse' @test
• Given the Turkish title "İstanbul Şehir Rehberi", with locale 'tr', returns 'istanbul-sehir-rehberi' @test
• Given the title "Räksmörgås" without a locale parameter, returns a slug using default transliteration 'raeksmoergas' @test
• Given an array of posts with mixed languages, returns correctly transliterated slugs for each based on their language property @test
