BTW, in your sample below, how can I get the underscore under the
previous character? (Otherwise, the underscore has no use.)
Hm, that was the idea of the example i sent earlier.

Hans,

many thanks for having fixed the issue with zeros and the new hyphenator.

I have discovered that \registerhyphenationexception doesn’t allow names
with first letter in capitals (only
\registerhyphenationexception[Nietz-sche] will work).

This differs from the \hyphenation command. Is this intended?

And sorry for asking this again, but I need underscore hyphenation with
the underscore character from the font and only for the \tex and
\hyphenatedurl commands (not for the rest of the text).

How could it be implemented in the following sample?

\setupcolor[state=start]
\setuplayout[backspace=95mm, width=middle]
\definetype[TeXcode][option=TEX, compact=absolute]
\unexpanded\def\tex#1{\normalexpanded{\TeXcode{\letterbackslash#1}}}
\starttext
\tex{thisisaverylongcommand}
\hyphenatedurl{http://optimisticwayofthinking.optimist}
\input knuth
\stoptext

Many thanks for your help again,

Pablo
