856180 - Bad display of certname(windowname) on certificate viewer for unicode intermediate certs

Status: RESOLVED DUPLICATE of bug 234856

(Core :: Security: PSM, defect)

Description

[Camilo Viecco (:cviecco)]

The displaymanages uses the cert.windowtitle idl, 

The return value of this function (getwindowtitle) is a utf8 string (at the c++ level as a char *). That is the cert nickname (ASCII), the common name (again usually ascii), and email address (ascii) or the subject name (UTF8!)

however the return value for this idl is a string 
https://mxr.mozilla.org/mozilla-central/source/security/manager/ssl/public/nsIX509Cert.idl#131

Which according to the string guide (https://developer.mozilla.org/en-US/docs/Mozilla_internal_string_guide#IDL_String_types) does not preserve the high bits (therefore does not work well the case of utf return)

To reproduce:
1. goto https://www.tp.edu.tw
2. open the certificate viewer
3. go to the tree view
4. notice the intemdiate cert with gibberish characters

I think we should either update the idl to a string type or create new unicode friendly windowName attribute (in nsIX509Cert4?)

problematic call: 
   *aWindowTitle = PL_strdup(mCert->subjectName);
