Tie in markup (lyrics)

[Stephan Schöll]

Hi everybody

I have stanzas 2..n put as markup below the score. In one stanza there
are two syllables on one note. In lyricmode I'd write the ~, but this
doesn't work in regular markup. Is there a way to add that kind of text
syllable tie to markup as well? Or should I simply look for some
tie-like unicode character?

\version "2.24.0"
\relative c' {
  c d e f
}
\addlyrics {
  he~yo he -- yo hey
}
\markup {
  "he~yo"
}


TIA Stephan
