All of them truncate the text file at 9025 bytes. The file is fully there, I've verified it with
cat from within Terminal Emulator. Is it a limitation of whatever common text display widget they use or something? It's really annoying...
EDIT: After trying AK Notepad I got to thinking that maybe it was something with the text files themselves (this is happening on multiple files). Each paragraph of text was a single line and each file had Unix-style line endings (line feeds). I first changed it so that each paragraph was formatted with LFs in all the right places; each text editor displayed exactly 1 more character than previous, in terms of the text (it was many more characters in terms of bytes, though, given all of the added LFs. Next I tried converting from LF to CR/LF (DOS-style endings). Now I got a dozen more characters of text (which was, again, many more bytes) but they all end at exactly the same spot. I'm really at a loss to explain it.
EDIT: I found and tried Amoeba and it has no problem with the file; it displays the original file (and the other versions) with no problems. But the interface is not that great (in particular, scrolling is exceptionally tedious). Any ideas out there?
