Can not create topic names like this: New_Topic_Name.
In previous version of TWiki I activated "Allow non WikiWord for the new topic name" and this worked fine.
When I activate this now, TWiki removes the underscore in the new topic name.
After saving then the topic like this "NewTopicName" I can go to rename it to "New_Topic_Name".

Hi Sebastian,

if anyone is still interested in a workaround - although the report is two years old - here is one, which works for my twiki4.3:

go to pub/TWiki/TWikiJavascripts and edit twikiString.pm. At the end of the file you find the definition for the variable MIXED_ALPHANUM_CHARS. Just add a + "_" before the ; . Thats it, as everything not in MIXED_ALPHANUM_CHARS is deleted during function "removePunctuation".

And I don't think that an underscore can do any harm ...

This is now fixed properly in SVN trunk and 5.0 branch.
