 Replying to [comment:3 JavierCasares]:
 > In the "intl" there are several functions.... some summary of use:

 I've just had a quick look through the search results and feel like I need
 to add a word of warning on the value of these as there appear to be quite
 some false positives due to the searches not being precise enough.


 That by no means invalidates the drive to get people to activate the
 extension as I totally agree the Intl extension really does add
 significant value if we could use it.

 It just means that the "plugin use" information as part of the making the
 case for recommending Intl is flawed.

 Checked the complete first page and only found 8 legitimate uses out of
 100 entries. Everything else was false positive, including the whole top
 five listed above. Most JS or PO files.


 > + [https://wpdirectory.net/search/01F3MVEAXY7YNREVV3Z93FBP7N Normalizer]

 Verified first x entries and found mostly correct. About 25% false
 positives from the Guzzle `README.md` file, some more false positives for
 namespaced classes also called Normalizer`. Rest mostly coming from the
 Symfony Iconv/Intl polyfills.

 > + [https://wpdirectory.net/search/01F3MVJAYM1Q9ETA2JFJP1C99X
 MessageFormatter]

 Verified first x entries and nearly all are false positives. Mostly use in
 comments or the Guzzle `UPGRADING.md` file. Only found two legitimate uses
 from the Symfony Intl polyfill.

 > + [https://wpdirectory.net/search/01F3MV5CPQPFQTZZ8Y940GZZR6 Collator]

 Verified first x entries and found mostly correct. About half coming from
 Symfony Intl Polyfill, the other half from a "free world map" function.
 Saw at least one false positive in a JS file.

 Verified first x entries and found mostly correct. Saw at least one false
 positive in a JS file.

 Verified first x entries and found correct. About half coming from Twig,
 the other half from Symfony Validator.

 Verified first x entries and found correct. About half coming from Twig.

 package.

 Some false positives for use in comments or translatable strings. Some
 real use.

 > + [https://wpdirectory.net/search/01F3MVW9NV0Y7NK45FSK9X9ENQ UConverter]

 Verified and found correct. Mostly found in a SimplePie code (not the WP
 Core version).

 Verified and found correct.
