Description djago 2002-11-13 07:07:17 UTC
I'm getting the primed symbol too separated from the letters when writting a
formula. I've tried with the example listed in the help (the example is
"f(t)=int from size*1.5 0 to 1 left[g(t')+sum from i=1 to N h_i(t')right]" and
in the picture looks perfect) but when I visualize the results, the ' appears as
a separated character (like a monospaced font). I've installed oo.643 from
scratch. When I was using oo1.0.1 the problem wasn't there (I have reformated
the HD and installed everything from ground up, so this is not an upgrade problem).

This problem was introduced unnoticed when we started usig the the 
I18N parseAnyToken function.
Comment 2 michael.ruess 2003-02-12 10:22:24 UTC
lowered priority to 4. Issue is not essential anyway.
Comment 3 thomas.lange 2003-02-14 08:49:22 UTC
The 'real' solution would be to explicitly define the ' as token for 
the parser, also the Math ML export should be changed to use sth like 
<msup> prime </msup>.

Since superscripts have a smaller fontsize this would require the 
prime character to be used to be about doubke the size of an 
apostrophe. For this the font needs to be changed. 
See also #i9121#.

For these reasons target should be OO 2.0.
Maybe we will have a new font then.

However since we don't know when we may get a font update we may 
implement a workaround in order that it looks correct (like in SO 
5.2) though it will not be the 'real' thing in view of the Math ML 
Comment 4 michael.ruess 2003-02-14 08:51:26 UTC
Changed Target to OO 2.0.
Comment 5 thomas.lange 2003-03-04 10:57:26 UTC
Note: the Unicode for the prime character in MathML is U02032.
Comment 6 rk 2004-03-20 22:28:14 UTC
I just finished writing my PhD dissertation in civil/structural engineering. 
Just wanted to bring to attention that at least in CE, primed symbols are used
frequently, e.g. concrete strength is represented by fc', steel vol. ratio =
%rho", etc. The work around for this problem for me was to keep spacing = 0, and
then insert small spaces (`), for all other characters (is there an easier way?).

As a short term fix, is it not possible to add a prime symbol to the special
symbol set, which is left aligned? 
Comment 7 Martin Hollmichel 2004-05-28 17:43:18 UTC
according to the announcement on releases
( this issue
will be re-targeted to OOo Later.
Comment 8 rk 2005-10-28 22:28:04 UTC
The same problem happens with subscripts (see issue 7819), which I suspect is a
related problem.  This seriously effects the usage of OOo for publishing papers
or writing patents.

Comment 10 thomas.lange 2005-11-01 08:38:56 UTC
tl->rk: The issue with the index has nothing to do with the one for the primed
Can be seen by using a non-italic character as base symbol.

Please don't make guesses about similarity of bugs. Just open a seperate issue
and of someone determines that it is the same issue one of them will be marked
as duplicate.
