Please generate svg for the following code on Windows using:
java -jar plantuml-1.2022.5.jar file.puml -verbose -charset UTF-8 -tsvg
where file.puml is as follows:
@startuml
a->b: hello/привет
note right
{{
c->d: hello/привет
}}
end note
@enduml
You'll get the following diagram (note that the encoding in the embedded part is broken):
Note:
1. If you use plantuml.1.2021.12.jar, then the encoding will be ok.
2. If you use Linux the encoding will be OK both for the plantuml.1.2021.12.jar and plantuml-1.2022.5.jar
3. It also works fine on plantuml server: http://www.plantuml.com/plantuml/svg/SoWkIImgAStDuU9CrBLBibB8ICt9oTU_iFzYmuKT5pPTs7gnYOipBxyaLQ4eCpsZX8kJixeQI70cwzgbO5VCMLlBnPcQbw80qiNb06I1J0S0
