Place Name Normalization - Quick Reference

What Changed

Improved place name normalization in generate-itinerary Edge Function to handle Turkish characters and spelling variations.

Before vs After

Before

const normalizedName = item.place_name.toLowerCase().trim()

After

const normalizedName = normalizePlaceName(item.place_name)

function normalizePlaceName(name: string): string {
  return name
    .toLowerCase()
    .trim()
    .replace(/ğ/g, 'g').replace(/ü/g, 'u').replace(/ş/g, 's')
    .replace(/ı/g, 'i').replace(/ö/g, 'o').replace(/ç/g, 'c')
    .replace(/Ğ/g, 'g').replace(/Ü/g, 'u').replace(/Ş/g, 's')
    .replace(/İ/g, 'i').replace(/Ö/g, 'o').replace(/Ç/g, 'c')
    .replace(/\s+/g, ' ')
    .replace(/\s*(open air museum|underground city|valley|village|castle|church)\s*$/i, 
      (match) => ' ' + match.trim().toLowerCase())
}

Examples

Input	Output	Benefit
"Göreme Open Air Museum"	"goreme open air museum"	Handles Turkish ö

"Çavuşin Köyü"	"cavusin koyu"	Normalizes all Turkish chars
" Love Valley "	"love valley"	Trims whitespace

Test Results

✓ All 7 test cases passed ✓ Turkish character normalization works ✓ Spacing normalization works ✓ Case normalization works ✓ Suffix normalization works
