The font you are seeing is LilyPond's standard music font, the Feta
font, and these are the letters used for dynamics.

The volta text is normally a number, and Feta has its own numbers
for that (which are similar to fingerings), therefore the text
under a volta bracket is typeset using a music font. If that
font doesn't contain any glyph for a particular letter, you
get a fallback text font. This is controlled through the font-encoding
property: fetaText → music font, latin1 → text font. Try


\version "2.24.0"

voltaDoubleCustom = #(define-music-function (repMusicCommon repEndingA 
repMusicA repEndingB repMusicB) (ly:music? markup? ly:music? markup? 
ly:music?) #{
  \set Score.repeatCommands = #'(start-repeat)
  $repMusicCommon

  \set Score.repeatCommands =
    #(list (list 'volta
                 #{ \markup \override #'(font-encoding . latin1) 
#repEndingA #}))
  $repMusicA

  \set Score.repeatCommands =
    #(list (list 'volta #f)
           'end-repeat
           (list 'volta
                 #{ \markup \override #'(font-encoding . latin1) 
#repEndingB #}))
  $repMusicB

  \set Score.repeatCommands = #'((volta #f))
#})

{
    \voltaDoubleCustom
        { c''8 8 8 8  8 8 8 8 }
        \markup "first"
        { c''8 8 8 8  8 8 8 8 }
        \markup "second"
        { c''8 8 8 8  8 8 8 8 }
}



There is a much simpler way, though:

\version "2.24.0"

{
  \repeat volta 2 {
    c''8 8 8 8  8 8 8 8
    \alternative {
      \volta 1 {
        \once \override Score.VoltaBracket.font-encoding = #'latin1
        \once \override Score.VoltaBracket.text = "first"
        c''8 8 8 8  8 8 8 8
      }
      \volta 2 {
        \once \override Score.VoltaBracket.font-encoding = #'latin1
        \once \override Score.VoltaBracket.text = "second"
        c''8 8 8 8  8 8 8 8
      }
    }
  }
}
