As another data point, we use text as the default, which is an alias for nohighlight and have had good results with it.
Have noticed some glitches from time to time, but overall this has been the best approach for us, and looks better raw, for example:
```text
jtl_name=$(/usr/local/bin/kubectl exec -it --namespace=$namespace $master_pod -- bash -c "ls -tr /*.jtl" | awk '{sub(/\r$/, ""); print}')
```
Producing:
jtl_name=$(/usr/local/bin/kubectl exec -it --namespace=$namespace $master_pod -- bash -c "ls -tr /*.jtl" | awk '{sub(/\r$/, ""); print}')
We have a custom icon for the default text fenced code block as well in composer.
