Description Roland Baudin 2023-04-03 08:44:32 UTC 
Description:
In Impress 7.5, it is now possible to get negative character spacing with large values. This could be used to get aligned subscript n and superscript m like in LaTeX formula x_n^m.

But in Writer, negative character spacing does not work the same. Though a negative spacing of -20pt can be specified, it is not applied (see test-char-spacing-writer.odt file), instead a small negative spacing seems to be applied.



Steps to Reproduce:
1) In Impress, write 'Example', select characters 'am', then Format / Character / Position and set Character spacing to -20 pt. Observe that the 'a' and 'm' are superposed, as expected.

2) Do the same as 1) in Writer. Observe that the 'a' and 'm' are not superposed.

The files test-char-spacing-writer.odt and test-char-spacing-impress.odt show the problem.

Tested with a fresh profile.
