[NTG-context] how to hyphenate SHA512?

Dear list, I have the following sample: \starttext \hsize\zeropoint hyphenation 8b2f3c087046c3943ace0dc4f958ef2138e58a51b40eef6fab6fa1aeb845cc25% 7a410ab1b914bc399b4293f31c76fc2c73e5be5ea4d329f9e6820984688efec2 \stoptext I plan to use underscore hyphenation. How can I get the SHA512 string hyphenated in any of its points? Many thanks for your help, Pablo -- http://www.ousia.tk
