New commits: commit 282b9ea0c0db18ed8177e2123996569d232c12a0 Author: Nelson Benítez León <nbenit...@gmail.com> Date: Fri Feb 12 11:47:38 2021 -0400 glib: keep same visual appearance between displayed and copied text When copying text from displayed document to the clipboard, we want a normalization that preserves 'canonical equivalence' i.e. that the text after normalization is not visually different than the original text. Our previous normalization was just preserving unicode 'compatibility'.
