Bug 139288

Created attachment 168535 [details]
screenshot showing that the language was applied to the field

Created attachment 168536 [details]
screenshot of my language settings

you see that I set already my locale to German

Please attach a sample file.

As far as I know, the language choice in Tools > Language menu doesn't affect date fields.  To make a field display dates to a particular language's convention (other than LibreOffice's locale setting, in your case English), the user needs to change the field explicitly.

To do so, select the field, Edit > Fields... menu, choose "Additional Formats..." in the Format column, change the "Language" dropdown list in the new Format dialog, then choose your desired format.

If these steps still don't work for you, please indeed attach a sample document to illustrate your problem.

Why not? I think this is a bug. I mean that's simply intuition: select the text and/or element and change its language.

It seems I am too untalented. I still cannot find there a language setting, see the screenshot attached.
(Btw. I also get this dialog on double-clicking on the field as alternative to use the menu.)

As you can see, there is no language selection.

Thanks. But what hidden/expert feature have you used to get this?
However, the English field appears here with CJK characters, see attached. Was this intentional or is this another bug?

I think the non-Latin characters should not appear right?
I got this by just opening your example file with LO 7.1RC1. I see that your document uses the font "Liberation Serif". However, using another font does not fix the issue.

I don't know the exact details, but AFAIK it affects linguistic features like spellchecking, hyphenation, etc., but not fields.  I agree intuitively it should also affect fields, and encourage you to file a separate bug about that.

You missed one step:

Please click the "Additional Formats..." entry of the Format column in your screenshot, and click "OK" button, then a new dialog will open, in which you can change the language for the field.

It's Chinese, because my Windows is in Chinese (although my LibreOffice is set to English UI).  It's not intentional, and is either some mistake of mine, or another bug.  I'll investigate later.

Done: bug 139415

Ah, many thanks!
So I am indeed to untalented. But this is very unintuitive and also no suitable workflow when you have several fields. Without your help, I would have never found out how to get the language right and the solution requires to open 2 dialogs. There should at least be a separate button to open the second dialog. As it is is is badly hidden.

Since I cannot get rid of the Chinese characters, despite I assured that everything is in English, it must be a bug. Can you please report it (since I don't know a way to get the Chinese characters and thus cannot provide the steps to reproduce).

Glad to help.

Yes I will once I've figured out all the details about how to reproduce the bug.  I'll leave a note here after I report it, too.

Also let's change the status out of INVALID since that one is usually reserved for spam.
