One problem I stumbled upon frequently is codebases that did not support localized formats, but just assumed a certain format to use, for example through concatenation. There are capabilities built into the programming languages, which allow to format numbers, currencies, etc. with a specific locale. There are also great resources [1] out there that provide all kinds of formats and localized names for countries, currencies, etc. [1] Unicode CLDR: https://github.com/unicode-org/cldr https://github.com/unicode-org/cldr
