Unicode "word joiner" (\u2060) won't work appropriate
Last modified: 2013-01-29 21:47:29 UTC
Unicode "word joiner" (\u2060) won't prevent line to break when remaining space in line becomes close to its minimum. The "word joiner" should keep two characters together and prevent for example line break. Hanging letter at the end of the line is not allowed in for example in polish language. You can insert "word joiner" (\u2060) when the Complex Text Layout is active (Tools>Options>...>CTL) from the menu. With \u2060 you can prevent single letter to stay at the end of the line by inserting \u2060 between the letter and <space> that comes after it. This mechanism doesn't work when the amount of remaining space is close to it's minimum, AND the \u2060 comes before <space>. TO REPRODUCE THIS ERROR 1) open plain writer document (all page and font settings should be dafault (Times New Roman, 12 pt), page margins set to 2,00 cm). 2) enter the text: Abcde fghij klmno pqrst uv w xyz. A b, cdefg hijk lmnopqr stu: „vwx, yzabc”. Def, ghijkmno p qr t uvwx yz. 3) enable field shadowing by pressing Ctrl-F8 or from Menu>View>Field Shadings 3) insert (\u2060) after single letter "t" that is at the end of the line (Menu>Insert>Formatting mark>No-width no break). 4) the grey rectangle will appear in the place of \u2060 and letter "t" will jump to next line, everything OK so far. 5) put any of these characters anywhere BEFORE u2060: <space>, ".", ",", ":", ";", "i", "j", "l", "t", "/", "\" 6) the \u2060 doesn't work anymore: letter "t"+u2060 jump back to previous line while the space next to it will be at the beginning of next line.

Created attachment 75478 [details] Example of not working word joiner (u2060)
I checked this on OOo 3.2.1 and 3.4-dev on WinXP, but I did not encounter the described behavior - the letter "t" was stuck to the succeeding space and word as expected. On which system do you run OOo? A special Linux distri and its by-packed OOo?
I run WinXP SP3. Please check my attachment (save it on a disk as it shouldn't be read-only) once again. I'm able to reproduce this error with the file I attached on all my machines (5 computers, XP SP3 on each) and probably on each computer at my work (different OS, mainly XP, but some Vista and 7- based computers, too, polish and english version of openoffice, portable and installed ones) - I've checked this on moreless twenty machines. I just see that when you try to copy-paste this "abcde..."-text (I don't believe that you have written it manually :) ) even as a plain text without formatting, it is being inserted with paragraph mark at the end of the first line. Hence, if you want to copy-paste it please use ^V (Paste>Special>Unformatted text) in a plain OOWriter document (Times New Roman 12, 2,00 cm (!) margins) and remove the last paragraph mark so the letter 't' would be at the end of the first line.
to polish speakers: the same issue is described here (in 2009): http://user.services.openoffice.org/pl/forum/viewtopic.php?f=8&t=63&p=345&hilit=sp%C3%B3jniki#p877 the file is attached too (it also works on my machine), and is confirmed on Ubuntu 9.10, Ooo 3.1. The author of cited post claims, that the only source file that contains \u2060 (x2060) is in "/i18npool/source/breakiterator/breakiterator_unicode.cxx", method "BreakIterator_Unicode::getLineBreak()", rows 405--420.
@siersciuch: In your document you have space after u2060 so the "word joiner" cannot work because you have no "word" after it but a space. This would work if you'd type a character AFTER the word joiner.
I had to reopen it. That IS a bug. If \u2060 doesn't joint the ' ' following it at all, it should not act in different ways depending on the space remaining within single line. I do understand that the ' ' is not a character but as you see \u2060 works as a "word joiner" until you diminish remaining space with given chars.
