Lokalisasi Semu: Uji Kesiapan i18n Tanpa Terjemahan Nyata

// Pseudo-localization transforms your source strings
// to simulate translation without real translators

// Original:
"Welcome to our application"

// Accented (simulates diacritics):
"[Ẁëľčöṁë ţö öüŕ àṗṗľïčàţïöñ]"

// Expanded (simulates text expansion ~30%):
"[Weeelcooomee tooo ouuur aaappliiicaaatiiioon]"

// Mirrored (simulates RTL layout):
"[noitacilppa ruo ot emocleW]"

// Brackets make untranslated strings immediately visible

// 1. Hardcoded strings (not wrapped in t())
// Pseudo strings have brackets/accents, so untranslated
// strings are immediately obvious in the UI

// 2. Text truncation
// Expanded text reveals buttons and labels that break
// when translations are longer than English

// 3. Layout issues
// Accented characters reveal font rendering problems
// RTL mode reveals directional layout bugs

// 4. Concatenation bugs
// "Hello " + name vs t('greeting', { name })
// Pseudo-localization breaks concatenated strings

// 5. Missing i18n wrappers
// Any string not going through the i18n system
// appears as plain English among pseudo text

// Strategy 1: Accented characters
// Replace ASCII with similar-looking Unicode
// a -> à, e -> ë, o -> ö, etc.
// Preserves readability while testing rendering

// Strategy 2: Text expansion
// Pad strings to simulate longer translations
// German is ~30% longer, Finnish ~40% longer
// Helps catch UI overflow early

// Strategy 3: Brackets/wrappers
// Wrap strings in [brackets] or «guillemets»
// Makes untranslated strings visually obvious

// Strategy 4: Bidi/RTL
// Mirror text for right-to-left testing
// Catches layout issues before Arabic/Hebrew testing

// Strategy 5: Combined
// Apply all strategies simultaneously
// Maximum coverage in one pass
