Invalid golang profile output format
I've recently started to try out the pprof tools from golang. I have followed the link https://golang.org/pkg/net/http/pprof/ to add a new http server to my service so the profile is able to be accessed.
All works fine, but when i try to generate a pdf or png output format, the text are all boxes as shown in the below image:
Is there any unicode libary that i need to install?
My service is deployed using docker alpine image
Solution
This is a common symptom of missing fonts.
Try installing the font-noto package:
apk add font-noto
