Worth investigating whether this affects gnome-documents too.

@Debarshi There is no such problem in gnome-documents I renamed one of my documents in google drive as Lac de l'Avellan and the title of the corresponding item in gnome-documents was normal.

You would have to have an item on a remote online account with such a name to test this. Just renaming an existing item from the application won't work.

@Debarshi Indeed I did the very same renamed my google drive document in google drive only and changes were automatically reflected in gnome documents.

I see, ok. In that case, indeed, gnome-documents seems fine.

I can reproduce this bug for Flickr albums too.

Here is a hint. This is a fall out from this commit:

commit f284c1e71108bbfaffc32aaf96326457726823e1

    main-toolbar: Escape markup when setting the toolbar title
    
    Use g_markup_printf_escaped() to properly escape strings.
    
    https://bugzilla.gnome.org/show_bug.cgi?id=702909


That patch should have escaped only those cases which use markup.

The titlebar now shows the title properly.

Works perfectly.
Tested with "Lac de l'Avellan" and my account on Flickr.

Thanks for the patch, Sparsh. It looks functionally correct to me.

The commit message needs some work. There is no need to have "Bug 702909" in the subject. The rest of the subject is a copy of the older commit that introduced the regression. The subject of your commit should be about your commit. eg., it could be "main-toolbar: Escape special characters only when using markup". See https://wiki.gnome.org/Git/CommitMessages for more details.

Do you usually write your name as "PaliwalSparsh"? Whatever you use in your commit will show up in the application's about dialog.

I am sorry for the mistake with the subject. And thanks for pointing out author name mistake or else I would have kept on doing it. I will certainly update it.

Thanks Sparsh. It looks much better now.

There is no need for "Use g_markup_printf_escaped() ..." in the commit message. If at all anything, we are removing unnecessary uses of the function. Just remove that line because it is misleading.

It should continue to be photos_base_item_get_name_with_fallback, not photos_base_item_get_name.

Thankyou, I have updated the code and commit message as you told.

Unfortunately, the fall out commit id is wrong. There is no such commit in our repository. I fixed it and committed the patch.
