I'm typesetting some medieval texts using a special font designed for
scholars. It contains the standard Latin character set, and some Latin
characters that were only used in former times (long S, R rotunda,
abbreviation signs). The latter are in the Private use area, but appear
as normal elements within a word. Now, the problem is that OOo inserts
automated linebreaks before the PUA characters (a bug maybe?).
For example (R = R rotunda, part of the PUA):
"succRescentibus" breaks into "succ
Rescentibus" at the end of a line
How do I prevent this, i.e. how do I tell OOo to ONLY break lines at
white spaces?
See http://www.unicode.org/reports/tr14/tr14-18.html for official
Unicode linebeaking algorthms. Private use characters are said to "have
as yet unknown line breaking behavior", that is any particular
linebreaking behavior must be specially tailored by an application. OOo
Writer allows no such tailoring, but allowing a break is as reasonable
as preventing one, especially since PUA characters are often special
symbols rather than letters.
Accordingly OOo Writer's behavior is not a bug.
But note also that the Unicode character U+2060 WORD JOINER is an
invisible non-spacing character intended as "glue" between characters to
prevent breaks. OOo Writer supports this character. It can be inserted
through Insert -> Formatting Mark -> No-width no break (short cut keys
Alt+I G B). If Field shadings are turned on, the character appears as a
narrow, grey, vertical bar, overlapping the preceding character and
following character.
This should allow you do do what you want. It also should work to
prevent breaks when text is converted to other formats that support Unicode.
