Yeah, this is what we were trying to hash out in  crbug.com/635850  back in August.

somebody already did this

but not everywhere, sorry, misunderstood

An advantage of the "Learn more" text is that it is being localized according to the current language. Whereas the English symbol for question mark "?" is not conveying the "learn more" meaning equally well in all languages.

Can we rethink this? Are there examples of other UIs that use a "?" icon across all languages?

@dpapad -- can you give examples of languages where it doesn't have the "learn more" meaning? It's the official MD "help" icon (see go/icons), so staying with it for consistency seems reasonable.

The question mark symbol "?" is not a symbol present in non-Latin based alphabets. For example in Greek the symbol for question mark is ";". Examples for other languages can be found at https://en.wikipedia.org/wiki/Question_mark#In_other_languages_and_scripts.

Issue 631195 has been merged into this issue.

Here ya go. This has the notes about using the icon instead of "learn more"

This is fixed

In the past, each content settings page had "learn more" as a separate row on the page. Since then, each "Learn more" row has been changed to a ? icon.

A separate issue raised by dpapad@ is how these icons are localized. That's an issue being tracked at  crbug.com/658700 , so I'm marking this as fixed.
