graphviz中组合变音符号的垂直对齐

Question

I have the following minimal dot code:

digraph {
    charset = utf8;
    rankdir = LR;
    "ε" -> "V" [label="V:V"];
    "ε" -> "ε" [label="C:C"];
    "V" -> "V" [label = "C:C"];
    "V" -> "ε" [label = "V:V́ "];
}

Note that the last V in the last line is followed by an acute combining diacritic (it is correctly combined with the V in my editor, FWIW). This diacritic does not appear high enough over the V after calling dot -Tpdf foo.dot -o foo.pdf . Instead, as you can see below, it is overlaid:

How do I fix this? I'm using dot version 2.38.0 on Ubuntu (xenial).

I think this works already. If you look closely at your image, you will see the diacritic:

I think it's just the font that needs to be changed. Referring to Graphviz: change font for the whole graph? , I modified your dot code and added a font:

digraph {
    graph [fontname = "helvetica"];
    node [fontname = "helvetica"];
    edge [fontname = "helvetica"];

    charset = utf8;
    ...

This is what I get:
