It appears that there are several issues with the interaction of fingering and
accidentals; we already have [#3692] as well as the fixed issues [#728] and
[#193]. Now this is the report by Pierre Perol-Schneider:
~~~~
:::TeX
\version "2.18.2" % or 2.19
<<
\clef "G_8"
\time 2/4 {
\set fingeringOrientations = #'(left)
| % mes.7
<e-1>8 fis <gis-1> a
} \\ {
\set fingeringOrientations = #'(left)
| % mes.7
<gis,-3>8 a,
%% uncomment the following line:
%\once \override Fingering.Y-extent = #'()
<b,-2> c
}
>>
~~~~
> The first fingerings are independently positioned while the second integrate
> the accidental sign to calculate the padding.
> This happend with sharp glyph only.
> I guess it has something to do with upper 'Y-extent from the fingering -- not
> from the accidental glyph(?) --, however I did not find any issue.
and more examples by Torsten Hämmerle:
> Fingering positions at the left concerned:
> 1. Why aren't the numbers placed below the accidental even if there's plenty
of space?
> 2. Why do numbers above an accidental overlap?
> This strange effect can be perfectly explained when assuming that horizontal
> positioning is done in a state where the numbers still sit on their baselines
> and these baselines are at the height of their corresponding notehead.
> After horizontal positioning, these numbers will be centred vertically, i.e.
> shifted down by half a staff-space (because they happen to be about a
> staff-space high).
> This shift will make them either overlap an accidental below or create an
> unnecessary gap.
> I've tried to illustrate this in the following PDF:
> [test-accidental-fingering2.pdf](http://lilypond.1069038.n5.nabble.com/file/t3887/test-accidental-fingering2.pdf)
and Thomas Morley (output attached):
>I tried to Y-center the Fingering-stencil.
> Though, with the example below the result is not all that convincing. If
> fingerings are 'right the default is already inconsistent, for different
> numbers.
> Additionally, if fingeringOrientations contains 'left or 'right a
> FingeringColumn is built at Staff-level, so the 'snap-radius-property comes
> into play.
> No real clue how to proceed...
> Here my testings:
