Mine seems escaped as hell, but still gets wrapped. Anything I'm missing?

edit: couldn't get UTF-8 branch symbol to be properly displayed here, but this is how it looks:

  function fancyPrompt {

   local bgBlue="\[\033[48;5;31m\]"
   local fgBlue="\[\033[38;5;31m\]"

   local fgWhite="\[\033[38;5;231m\]"

   local bgDarkBlue="\[\033[48;5;24m\]"
   local fgDarkBlue="\[\033[38;5;24m\]"

   local bgDarkGray="\[\033[48;5;237m\]"
   local bgLightGray="\[\033[48;5;245m\]"
   local fgLightGray="\[\033[38;5;245m\]"
   local colorClear="\[\033[0m"

   local branch
   local branch_symbol="\[\] "

   if branch=$( { git symbolic-ref --quiet HEAD || git rev-parse --short HEAD; } 2>/dev/null ); then
   	branch=${branch##*/}
   	export PS1="${bgBlue}${fgWhite}\h${colorClear}${fgBlue}${bgDarkBlue}\[\] ${fgWhite}\w${bgLightGray}${fgDarkBlue}\[\] ${fgWhite}${branch_symbol}${branch}${fgLightGray}${bgDarkGray}\[\] ${colorClear}"
   else
   	export PS1="${bgBlue}${fgWhite}\h${colorClear}${fgBlue}${bgDarkBlue}\[\] ${fgWhite}\w${bgDarkGray}${fgDarkBlue}\[\] ${colorClear}"
   fi

 }
