Escape characters in doc.Strings

Hi,

I ran into an issue where I could not purge some usertext entries with python rhinoscript
specifically these type of entries:

In userdata.py the method GetDocumentUserText pointed to the cause, apparently there was a need to filter escape characters for reasons unknown to me:
I

    #todo: leaky abstraction: "\\" logic should be inside doc.Strings implementation
    keys = [scriptcontext.doc.Strings.GetKey(i) for i in range(scriptcontext.doc.Strings.Count) if not "\\" in scriptcontext.doc.Strings.GetKey(i)]

I’d like to purge the document form all userdata and want do it like so:

import rhinoscriptsyntax as rs
import scriptcontext as sc

keys = [sc.doc.Strings.GetKey(i) for i in range(sc.doc.Strings.Count)]
for key in keys:
    rs.SetDocumentUserText(str(key),'')

It clears all entries including those with the escape-characters.
However given the comment in the python method, I’d like to know if and what danger there lies in not filtering out keys with escape characters.

Thanks

I’m looking at this a bit more. Brb

Hi,
As far as I can tell there may have been a time where rs.SetDocumentUserText didn’t accept escape characters but I can’t see a good reason for applying the filter now.
