Sort an array

Before I push this to staging, make the sorting easy for reviewers: put the comparator in a named function compareCaseInsensitive, ensure stable behavior with accented characters by using localeCompare with 'en' and sensitivity 'base', and keep the example array small so a reviewer can eyeball the order quickly.

I merged a list and then sorted it with arr.sort(), but accented names like 'Émile' appear after 'Zoe' unexpectedly. I don't know whether to use localeCompare or normalize the strings first. Which is the likely cause and which fix will work across browsers for English and French users?

Every release we face UI complaints about ordering: case differences, accents, and numeric substrings all behave inconsistently across components. I need a single sorting policy I can apply everywhere to reduce review back-and-forth. What habit or small utility function should the team adopt to make sorting predictable across locales?
