    \usepackage[T1]{fontenc} should help

  • @ChristianHupfer I don't like to use T1 because of The default Computer Modern font does not support T1 see LaTeX wikibook chapter 9.5

    Use $<2.5$,$<3.00$,$<3.5$,$<4.00$ instead. Oct 3, 2017 at 9:11

    There is no reason not to use [T1] encoding. You still will get the same look. Try it out. (It is neverless interesting to find out, why \textless loops) Oct 3, 2017 at 9:12

As default hyperref use the values not only as label for the fields, but also as export value for the form. This can be problematic if the values contains complicated commands meant for typesetting. In such cases you can set explicit (simpler) export values with a keyval syntax: The difference between the displayed text an the value can be seen if you add a button to show the value of the field (which also the one who would be exported or sent to a script):




\ChoiceMenu[radio,name=result,default=A]{Result:}{\textless 2.5=A,\textless 3.5=B,\textless 4.5=C}

\PushButton[onclick={app.alert("The value is " + this.getField("result").value)}]{Submit}

    @GuM The official hyperref documentation is very sketchy as far as PDF forms are concerned, but @NicolaTalbot's freely accessible book contains a nice overview.
