That works great to replace all spaces. However, as a casual observer, I'm not sure this is what was asked. Were all the spaces to be replaced with the non-breaking spaces, or just those after the first one, leaving one space without the replacement. So: `"the lazy  brown   fox    jumped..."` [download] But I would like to expand the question a bit. I would like to see all spaces removed with the exception of just one separating the words, and then have that replace with the non-breaking space.

Were all the spaces to be replaced with the non-breaking spaces, or just those after the first one, leaving one space without the replacement. So: `"the lazy  brown   fox    jumped..."` [download] This should work: `$foo =~ s/(?<= )( +)/' ' x length($1)/ge` [download] But I would like to expand the question a bit. I would like to see all spaces removed with the exception of just one separating the words, and then have that replace with the non-breaking space. So: `"the lazy brown fox jumped..."` [download] Can be solved thusly: `$foo =~ s/ {2,}/ /g;` [download] I believe this answers both requests unless I am misreading something. -enlil	[reply] [d/l] [select]
