When content is markdown or html, Umlauts must be given escaped (ü), even if markdown file is UTF-8. Works with Umlauts (äü), when content is given as code string.

When using this, the page always pops to the top when the help button is clicked. Any fix to this?

I used to be able to write HTML inside content, but in the new Shiny version HTML is displayed as text. For example,

helpPopup(title = paste0('Choose significance level ', HTML('α')), content = 'something' )

is displayed as "Choose significance level α" (WHERE α is shown as the actual code for alpha, i.e. is SPELLED OUT &ALPHA; )

Does anyone have an idea how to use the function when calling it in the server.R inside renderUI and calling it in the ui.R with uiOutput? Thanks

I can't get the helpPopup to display HTML either. helpPopup(title=NULL,content=HTML("I like <b>pie</b>.") just displays plain text: I like <b>pie</b>. instead of I like pie.
