Ian, thanks for the solution!
Devon, the CRLFs come from the fact that the data source was a text editor. I imported the file as string and wanted to reshape it into a character matrix to subsequently strip the last two columns to get rid of the CRLFs when I stumbled over the two-byte-character issue. This is part of an approach to solve one of those word-search puzzles where one is given a rectangular letter array and has to find all the words which can run in any of the eight principal directions. What I still need is an elegant expression that converts a character matrix into its diagonal strings (as an array of strings or another array), like: ]original=. 3 4$'ABCDEFGHIJKL' ABCD EFGH IJKL diag original A BE CFI DGJ HK L I'm currently trying some index magic, but I think there may be a more direct approach.
