Problems with labels in QGIS 2.10

Question

I want to label my polygons with information, and I want the labels to be in two rows - name on row 1 och volume on row 2. My problem is, that I get an extra "quare" at the end of row 1? That has never happened before.

EDIT: Here is the expression I wroght:

And, it works, I just get that extra quare, like this:

I use QGIS 2.10 and Windows 10, could it be because of the Windows 10? I never had this problem on Windows 8.

EDIT 2: I realize that I need to clarify my question, I have two different columns. I want the information in column 1 to be in the first row and the information from column 2 to be in the second row of the labels. But, my expression makes the labels with an extra square at the end of row 1.

I use encoding windows-1252.

Answer 1

The expression editor lets you wrap text from one line to the next.

I think the square may be part of a newline. In Windows, newline is two characters (\r\n), on Linux it's one (\n). What you did works on Linux (in QGIS 2.12 at least). Not sure why it would work in Windows 8 - perhaps this was in an earlier version of QGIS which may have handled newlines differently?

An easier way - as Jakob mentioned - is to choose a special character to break the text over lines. This can be any character - just make sure that it's one that won't appear in your label text. Here, I've chosen *. I've put this after "FASTIGHET" - that seems to be where you want the split.

"FASTIGHET" || '*' || CASE WHEN "Blad1_Field1" is '' THEN '' ELSE 'Volym (m3sk)' || ' ' || "Blad1_Field2" END

You can now use the Formatting > Wrap on Character setting, and your label should appear over two lines.
