If I am not mistaken SHA is only hexadecimal digits, so you probably need only to have a « language » that hyphenates between any pair of those. Should be much simpler I guess, but I do not really know how to add such setting I am afraid.

Many thanks for your reply, Joseph.

The underscore I want to use should be placed below the previous
character, such as in (code from Hans):

    \startluacode

        function document.addfunnyhyphen(tfmdata)
            local underscore = utf.byte("_")
            local char       = tfmdata.characters[underscore]
            if not char then return end
            tfmdata.characters[0xFE000]   = {
                width    = 0,
                height   = 0,
                depth    = 0,
                commands = {
                    { "right", -char.width },
                    { "down", char.depth },
                    { "slot", 1, underscore },
                }
            }
        end


    utilities.sequencers.appendaction("aftercopyingcharacters",
    "after","document.addfunnyhyphen")

    \stopluacode

    \definehyphenationfeatures
        [underscore]
        [righthyphenchar="FE000]

    \setuphyphenation
        [method=traditional]

    \sethyphenationfeatures
        [underscore]
    \starttext
    \hsize\zeropoint

    hyphenation
    \stoptext

Is there no way to define a language that hyphenates any pair of characters?

Many thanks for your help,

Pablo
