7 June 2018 update: note that the application referred to in this article is actually part of the product in Studio 2015 onwards. So no need to download it!
English spoken in Australia, Belize, Canada, Caribbean, India, Ireland, Jamaica, Malaysia, New Zealand, Republic of the Philippines, Singapore, South Africa, Trinidad and Tobago, United Kingdom, United States and Zimbabwe. Also known as en-AU, en-BZ, en-CA, en-029, en-IN, en-IE, en-JM, en-MY, en-NZ, en-PH, en-SG, en-ZA, en-TT, en-GB, en-US and en-ZW. These are the language codes used by Microsoft in their National Language Support (NLS) API Reference for the different flavours of English supported and this is what Studio bases its language support for English on… then it’s further complicated as it can also vary depending on the operating system of your computer (Win XP, Vista, Win7 etc.)
Of course this is English, or flavours of it. But there are differences and Studio always insists on knowing which flavour of any language is being used. So 16 variants… and it’s even more with Spanish for example where we have 20 variants.
So does it really matter that 23/08/2005 in the United Kingdom is written as 8/23/2005 in the United States, or that 1,234,567,890,123.45 in the United States is written in Spain (Spanish (Spain)) as 1.234.567.890.123,45?
