CentOS 7.0.1 x64

which locale is that ?

pt_br. But The Weekdays station in English with exception of Friday being displayed incorrectly.

Looks like translation is wrong in locale/pt_BR/LC_MESSAGES/frontend.po:

#: jsLoader.php:129
msgctxt "Friday short"
msgid "F"
msgstr "S"

Just a quick example how do people translate it:

# STRING='"Friday short"'; grep -r -A2 "msgctxt $STRING" * | grep -Ev "msgstr \"\"|$STRING|--|msgid"
bg/LC_MESSAGES/frontend.po-msgstr "Пт"
cs/LC_MESSAGES/frontend.po-msgstr "Pá"
de/LC_MESSAGES/frontend.po-msgstr "Fr"
el/LC_MESSAGES/frontend.po-msgstr "Π"
en_US/LC_MESSAGES/frontend.po-msgstr "F"
es/LC_MESSAGES/frontend.po-msgstr "V"
fr/LC_MESSAGES/frontend.po-msgstr "F"
id/LC_MESSAGES/frontend.po-msgstr "F"
it/LC_MESSAGES/frontend.po-msgstr "V"
ja/LC_MESSAGES/frontend.po-msgstr "F"
ko/LC_MESSAGES/frontend.po-msgstr "F"
lv/LC_MESSAGES/frontend.po-msgstr "P"
nl/LC_MESSAGES/frontend.po-msgstr "F"
pl/LC_MESSAGES/frontend.po-msgstr "P"
pt_BR/LC_MESSAGES/frontend.po-msgstr "S"
pt_PT/LC_MESSAGES/frontend.po-msgstr "F"
ro/LC_MESSAGES/frontend.po-msgstr "F"
ru/LC_MESSAGES/frontend.po-msgstr "Пт"
sk/LC_MESSAGES/frontend.po-msgstr "Pi"
tr/LC_MESSAGES/frontend.po-msgstr "Cum"
uk/LC_MESSAGES/frontend.po-msgstr "Пт"
vi/LC_MESSAGES/frontend.po-msgstr "F"
zh_CN/LC_MESSAGES/frontend.po-msgstr "F"
zh_TW/LC_MESSAGES/frontend.po-msgstr "F"

I've requested translators in the mail-list to take a look and fix it.
I'm not able to fix such things myself, waiting confirmation when it will be fixed in Pootle.

Hi Miguel, thanks for report.

The "S" for friday is right on PT-BR... the error is on another days (like Monday, Wednesday, Thursday, Sunday).
The correctly is:
Monday - S
Tuesday - T
Wednesday - Q
Thursday - Q
Friday - S
Saturday - S
Sunday - D

And now... a very old request: how search on pootle for the exactly text ? If we search for "S" we will found almost 3.000 results...

Current status:
OK - Monday - S
OK - Tuesday - T
OK - Wednesday - Q
OK - Thursday - Q
OK - Friday - S
OK - Saturday - S
OK - Sunday - D

I change too some another errors (like Time -> "Data" and "y" -> "y" | changed to "Time" -> "Hora" and "y" -> "a")

Many times the context is very important for this...

But I think now is ok... if found some more "translation bug" please send again

Thanks everyone for the quick fix. I had already set here but the product would be with these bugs. Thank you!

Performed changes will be synced to svn really soon, and they will be available in release 3.0.3
I'll add more details here a bit later.

I've replied to the mail list already, copy-pasting here just in case:

One nice new feature of upgraded recently Pootle may help you:

• open list of translatable strings, as usually;
• bottom of the page find "Export View" link, click it;
• search over the page for "Friday short" and on right find a direct link to required string to translate it.
