Bulgaria formatting implementation notes
For Bulgaria, format numbers with the explicit locale bg-BG; the reference value 1234567.89 renders as 1 234 567,89.
Bulgaria's reference format uses "," as the decimal mark and a non-breaking space (U+00A0) for grouping. The integer uses repeating groups of three digits. Pass "bg-BG" directly to Intl.NumberFormat instead of replacing punctuation in a preformatted string.
EUR is shown with € after the amount with a separating space; the same reference value renders as 1 234 567,89 €. The percent sign appears immediately after the amount. Use the ISO currency code for storage and interchange because a visible symbol can be shared by unrelated currencies.
Western 0–9 digits are the page's reference digit system, and the negative pattern is -n. Treat bg-BG as the reference locale for this page, but still respect the user's explicitly selected language and numbering-system preferences. Validate output with formatToParts() when spacing, signs, or bidirectional literals affect the interface.
- Locale: bg-BG
- Decimal and grouping: 1 234 567,89
- Currency: EUR → 1 234 567,89 €
- Digits: Western 0–9 digits

What's different here
- Decimal mark is a comma (,) (en-US uses a period (.)).
- Thousands are grouped with a no-break space (U+00A0) (en-US uses a comma (,)).
- The currency symbol goes after the amount with a space (en-US: immediately before the amount).
- Uses the same number pattern (decimal mark, grouping, symbol and percent placement) as Poland.
- Nearby differences: Italy (it-IT) groups with a period (.) instead of a no-break space (U+00A0); Spain (es-ES) groups with a period (.) instead of a no-break space (U+00A0); Sweden (sv-SE) places the percent sign after the number with a space; Norway (nb-NO) places the percent sign after the number with a space.
- Currency: EUR has ISO minor unit 2.
- The grouping character is a no-break space (U+00A0), not a regular space. Normalise it before parsing user input or comparing strings.
- Postal address order: name → building → street + street number → district → postcode + city → country. See address formats.
