Umlauts causing error on build

[sgaechter]

Umlauts, as common in German Language (like: ä, ö, ü) causing problems buildung Sphinx Docs. The infected Charts are replaced by "Syntax error in graph mermaid version 8.13.7":

Error Message displayed in Doc:

As soon as all umlauts are replaced, the graphs will be displayed as expected.
Tested make commands: html, latexpdf

Example:

`.. mermaid::

flowchart LR
a(Kundeninput) --> b(Product-Backlog) --> c(Sprintplanung) --> e("Sprint (2-4 Wochen)") --> f(Sprint-Review) --> g([Zum Veröffentlichungsprozess])
e --> d(Sprint-Retrospektive) --> c`

When I build the mermaid chart with mermaid-cli the umlauts are built correct (see output.png below):

used version: Master (a6c1f8b)

I've tested this and looks ok

@mgaitan The Screenshot with the diagram you see in my Post is not the result in the rendered sphinx doc. I've rendered this with the online tool. Mermaid still throws an error and only the Error - Placeholder is shown in the doc.

@sgaechter the screenshot I've posted was after copying/pasting your diagram code in a .rst file and then building html with sphinx. Is it not the issue reported?
In such a case, could you share an online example of a source and the produced html

[sgaechter]

@mgaitan I tested the output again. Unfortunately, either the HTML or latexpdf is rendered correctly on my side:
Source

HTML:

latexpdf:

as soon as I replace the umlaut "ö" to "oe " the rendering works as expected:
HTML:

latexpfdf

Attached you can find the full source code of the sphinx-Project. I'd be pleased if somebody can tell me what's wrong.

Used versions in requirements.txt

I've tested to set the Word with umlauts in Colons: g(["Zum Veröffentlichungsprozess"]).
This resulted in the output no longer bringing an error. However, the character encoding does not seem to be correct:
HTML:

latexpdf:

I also added the directive source_encoding = 'utf-8-sig' to config.py, with no effect.

Issue still open also with latest release.

This is still a problem. The following line in a sankey-beta diagram causes a Diagram syntax error:

Kein Angebot, hätte angenommen, 3

Error: Error: Parse error on line 17: ...t, 1Kein Angebot, hätte angenommen, 3 ----------------------^ Expecting 'NEWLINE', 'EOF', 'COMMA', got 'NON_ESCAPED_TEXT'
