There's about 500 of them.
They appear when building:
//chrome/android:chrome_java
E.g.:
../../../../../../tmp/tmpd3ZOHh/r3/values-de/android_chrome_strings.xml:60 Replace "..." with ellipsis character (…, …) ?: TypographyEllipsis [warning]
<string name="section_saved_passwords_exceptions">"Nie speichern für..."</string>
Somewhat related bug for Android:
https://bugs.chromium.org/p/chromium/issues/detail?id=554223
Decision was to use the ellipsis characters rather than three-manual dots. I agree with ainslie@ it's nicest if they just all match, but perhaps that helps with precedent.
