Based on an underlying filesystem supporting a maximum of 255 characters in
filenames, here is the maximum possible filename length depending on the choosen
encoding scheme : stream (189), block (176), block32 (143). Note that we should
rather talk about bytes, when filenames contain special (multi-bytes) characters.
Prior to version 1.1, only stream encoding was supported. Prior to version 1.1, only stream encoding was supported.
