Tabs not being treated as invalid
Closed this issue · 0 comments
I ran across an issue where there was a tab at the end of an NMToken but it was still passing validation
The quick fix is to change the following line error on any whitespace, including tabs
Line 1268 in 2e3529e
However, from my reading, tabs are not valid characters except in terminal control set values) and needs to fail validation whether at the end or the beginning or the middle of the string.
