In bug 530109, the fallback encoding for the Esperanto locale was changed to UTF-8. As far as I can tell, no data was presented as the motivation of the change. We now have telemetry data that indicates that Esperanto is locale where users most often resort to using the character encoding override. This is bad for the user experience. See https://bug906032.bugzilla.mozilla.org/attachment.cgi?id=796536 Please change the fallback encoding (intl.charset.default) to windows-1252 for the reasons given in https://developer.mozilla.org/en-US/docs/Localizations_and_character_encodings

Ok, I'm ready to change it, but from what I seem in central at least, many locales (en-US, es-AR, de, fr, fi, pt-BR, da, ...) are using ISO-8859-1. Is it ok to use that instead of windows-1252? I don't know why this https://bug906032.bugzilla.mozilla.org/attachment.cgi?id=796536 lists windows-1252 as fallback for, say, French when release[1], beta[2], aurora[3] and central[4] for that locale use iso-8859-1. So, do I go for iso-8859-1? [1] http://transvision.mozfr.org/?repo=release&sourcelocale=en-US&locale=fr&search_type=entities&recherche=intl.charset.default [2] http://transvision.mozfr.org/?repo=beta&sourcelocale=en-US&locale=fr&search_type=entities&recherche=intl.charset.default [3] http://transvision.mozfr.org/?repo=aurora&sourcelocale=en-US&locale=fr&search_type=entities&recherche=intl.charset.default [4] http://transvision.mozfr.org/?repo=central&sourcelocale=en-US&locale=fr&search_type=entities&recherche=intl.charset.default

iso-8859-1 is mapped to windows-1252 by the encoding system. They're identical.

Ok then, it's done. These are the commits for Central, Aurora and Beta (with sign-offs for Aurora and Beta): http://hg.mozilla.org/l10n-central/eo/rev/710c6b6c75fc http://hg.mozilla.org/releases/l10n/mozilla-beta/eo/rev/d8c2584fed66 http://hg.mozilla.org/releases/l10n/mozilla-aurora/eo/rev/e1ee50ae2e8e Thanks for reporting the issue.

Thank you!
