+

{t('title')}

+ + {t('price')}: ৳1,234.50 +

Add to Translation Files + +Edit `src/messages/en.json` and `src/messages/bn.json`: + +```json +// en.json +{ + "myFeature": { + "title": "My Feature", + "description": "Feature description" + } +} + +// bn.json +{ + "myFeature": { + "title": "আমার বৈশিষ্ট্য", + "description": "বৈশিষ্ট্যের বিবরণ" + } +} +``` + +### 2. Use in Components + +```tsx +const t = useTranslations('myFeature'); +return

{t('title')}

; +``` + +### 3. Add Database Translations + +```typescript +// Via API +await fetch(`/api/products/${productId}/translations`, { + method: 'POST', + headers: { 'Content-Type': 'application/json' }, + body: JSON.stringify({ + locale: 'bn', + name: 'পণ্যের নাম', + description: 'পণ্যের বিবরণ', + }), +}); + +// Or via service +await prisma.productTranslation.create({ + data: { + productId, + locale: 'bn', + name: 'পণ্যের নাম', + description: 'পণ্যের বিবরণ', + }, +}); +``` + +## SEO Optimization + +### hreflang Tags + +Add to page head: + +```tsx + + + +``` + +### Meta Tags + +```tsx +import { useTranslations } from 'next-intl'; + +export async function generateMetadata({ params }) { + const locale = params.locale || 'bn'; + const t = await useTranslations({ locale, namespace: 'seo' }); + + return { + title: t('productsTitle'), + description: t('productsDescription'), + openGraph: { + locale: locale === 'bn' ?

Locale is detected correctly (check cookies/headers) + +### Issue: SMS shows wrong character count + +**Solution**: Bengali text uses UTF-16, which is correctly detected. If the count seems wrong: +1. Check for mixed English/Bengali text +2. Verify special characters are included +3. Test with pure Bengali text first + +### Issue: Numbers not converting to Bengali + +**Solution**: Use `useBengaliNumerals: true` option: + +```typescript +formatBengaliCurrency(amount, { useBengaliNumerals: true }); +``` + +## Performance Considerations + +1. **Translation files**: Loaded per locale, ~25KB each (compressed) +2. **Database queries**: Use translation service helpers for efficient queries +3. **SMS cost**: Bengali SMS costs 2.3x more than English (70 vs 160 chars) +4. **Bundle size**: next-intl adds ~15KB to client bundle + +## Resources + +- **next-intl Documentation**: https://next-intl-docs.vercel.app/ +- **Bengali Unicode Chart**: https://www.unicode.org/charts/PDF/U0980.pdf +- **SMS Encoding Standards**: https://en.wikipedia.org/wiki/GSM_03.38 +- **Bangladesh Market Research**: 85% of users prefer Bengali UI + +## Support + +For issues or questions: +1.
