[Qgis-user] Labeling with subscript

[Andreas Neumann]

Hi Christian,

You probably don't do anything wrong. It is just not supported (yet).

Here is the subset of HTML that should work:

  	* font-color 
(https://www.qgis.org/en/site/forusers/visualchangelog314/index.html#feature-respect-html-colors-in-labels)
  	* font-familiy 
(https://www.qgis.org/en/site/forusers/visualchangelog328/index.html#feature-add-support-for-html-bold-italic-font-size-and-font-family-to-labelling 
)
  	* font-size
  	* bold
  	* italic

This is a really small subset of HTML that is supported until now, 
because many HTML formatting options have an impact on text geometries 
and need to be taken into account in the label engine (e.g for overlap 
tests, etc.)

If you need this implemented, please ask a developer for a quote to get 
it implemented. Nyall Dawson (https://north-road.com/) did most of the 
work here. He could be asked.

Hope this helps,

Andreas
