Hmm, there are 2 issues , all percentages are different, and count for dy is different {6952} , all the other counts are the same, currently investigating { best guess atm is newlines and EVA( ' ) } -

In case you can use it for comparison, here is my cleaned up file:

Thanks for the file bi3mw, that helped find the issue.
<-> A drawing intrusion in the text.
<%>kchsy.chydaiin.ol<->o,l,tchey.char.cfhar,am {ZL3a-n.txt} [line 71] <f1v.1,@P0>
kchsy chydaiin olo l tchey char cfhar am {ZLall2.txt} [line 32]
kchsy chydaiin ol o l tchey char cfhar am {ZL3_W.txt) [line 32]
There are 8 of these strings "d<->y" in ZL3a-n.txt and when the drawing intrusion is removed it results in a new 'dy' string.
It is possible that you may not be using the latest version of ivtt or my codeblocks ming compiler has not updated to the C17 revision . -

Very nice, "onlinetoolz" also fits. The only thing that doesn't fit anymore is the output in my text editor (rather mysterious). For example, it shows 4581 for II. -

Oh yeah, same here, aha i think its the triples like 'daiiirihy'. in notepad++ it highlights them and it only only highlights 2 of the 3 i's
but ngrams would be ['da', 'ai', 'ii', 'ii', 'ir', 'ri', 'ih', 'hy'].
EDIT:
Oh noes , i think i see another issue, grrr. i dont think EVA(-') is being processed properly, Oh well , it'll have to wait till tomorrow now. -

You are right, if you subtract the 184 "iii(i)" from the 4765 "ii" then you get exactly 4581. So everything is fine ( hooray )
So we have fulfilled Rene's requirements (same results from cryptool and python script, see post #45).
