Hi,
say I have arbitrary string of alphanumeric characters:
\starttext
\showframe
9769387937933hhgiuiuziuziduzid93739837fhieuhifeuhfeiu39739837938398zfhfdkuhfiufhz398739837r98z379dihhfiu
\stoptext
In mkiv make a lua script using gsub, i.e. something like
s='9769387937933hhgiuiuziuziduzid93739837fhieuhifeuhfeiu39739837938398zfhfdkuhfiufhz398739837r98z379dihhfiu'
s= string.gsub(s,'(.)',"%1\\hskip0sp")
\starttext
\startluacode
s='9769387937933hhgiuiuziuziduzid93739837fhieuhifeuhfeiu39739837938398zfhfdkuhfiufhz398739837r98z379dihhfiu'
s= string.gsub(s..s..s,'(.)',"%1\\hskip0sp")
context(s)
\stopluacode
\stoptext
... ok, compared to this solution it is for sure easier to manually add \crlf  :o))

The background are hundreds of URL's, which are part of regular text ... now transformed in a complicated but working beast:
\startbuffer[myurl:01]\catcode`\%=12 \catcode`\_=12 \catcode`\&=12 \catcode`\#=12\setupalign[line,block,hanging]\useURL[test][http://www.lfd.m-v.de/dschutz/beschlue/ent49.html#nr.5][][http://www.lfd.m-v.de/dschutz/beschlue/ent49.html#nr.5]\from[test]\removeunwantedspaces\stopbuffer\getbuffer[myurl:01]

If I now again add your lines of luacode too, I go crazy :o)

Is there no handy little context command that could just be pasted before the string, like the following?
\useURL[...][...][][\ThisHelps 9769387937933hhgiuiuziuziduzid93739837fhieuhifeuhfeiu39739837938398zfhfdkuhfiufhz398739837r98z379dihhfiu]
