Re: International Standards Organization
There are multiple "language" options for software that are independent of each other:
1. UI language -> what the menus, dialogs etc are displayed in
2. locale -> basis for units such as dates, temperatures, weights and measures
3. doc language -> for instance a word processor can display, edit and proof text from dozens of languages in a single document, although you might need to download add-ons for specific tasks such as Finnish hyphenation.
Problems (usually worst in Anglophone countries, but officially multi-lingual places like Canada and Switzerland have their own issues)
1. (not as bad as before) Manufacturers distribute computers with US English settings that are never reconfigured by the user or IT department to meet local expectations. Consequently every bit of software subsequently installed reads the system default and matches settings.
2. Vendors confusingly conflate the different language settings, often using the locale names (e.g. English (US), English (New Zealand), French (France), German (Switzerland) ) in place of language names.
3. Browsers download as US English and ignore the system settings. Each browser has its own complement of language and locale settings to cover date display, spell-checking etc.
4. Online software is generally worse at handling this than desktop software. For instance Microsoft 365 seems to have US date formats hard-coded all over SharePoint, OneDrive, Teams etc so that any string 01/02/03 could be a dd/mm/yy or mm/dd/yy depending on the browser you open it in or indeed if you open a document in a desktop app rather than online. Google. Apple, Facebook and Amazon have similar problems across their platforms and services. Websites also perform weird redirects based on language to subdomains in different locales.
5. Most of the developers (even in open-source land) are in the US and cannot be bothered fixing bugs to do with non-US issues. There are bugs in Chromium relating to such stuff that go back over a decade, and are constantly merged and deferred.
