Page language code (titles, descriptions, UI text). Country and language are separate: you can search a marketplace in a non-default language (e.g. DE + en_GB). Supported languages vary by country — US: en_US, es_US | CA: en_CA, fr_CA | MX: es_MX | BR: pt_BR | GB: en_GB | IE: en_IE | FR: fr_FR, en_GB | DE: de_DE, en_GB, nl_NL, pl_PL, tr_TR | IT: it_IT, en_GB | ES: es_ES, pt_PT, en_GB | NL: nl_NL, en_GB | SE: sv_SE, en_GB | PL: pl_PL | BE: fr_BE, nl_BE, en_GB | JP: ja_JP, en_US, zh_CN | AU: en_AU | IN: en_IN | SG: en_SG | AE: ar_AE, en_AE | SA: ar_AE, en_AE | TR: tr_TR | EG: ar_AE, en_AE | ZA: en_ZA. If the code is not supported for the selected country, the Actor falls back to that country's default.
