Both method (yours and Christopher2222) worked.  But I had to do some changes in the source file first.  Looking at the first three characters of str (after I saved it as one line of 2024 characters in utf-8), I realized that they were not part of the initial line that start in fact with a m (so it was a false location - 935 instead of 932).  So I went back to the source file and realize that, in the line, they were a bunch of "space" characters.  So with Notepad++, I delete them and save the file again by converting the line with ANSI code this time.  Reloading  and executing the Maple file seams to have solve the problem.

I am happy to have use the StringTools package.  All I need to do is to check if it's working under Linux and a way to see, say, the five letters befor and after the Qxp+zr6km.  But I can do it with my text editor so why bother in Maple?  By the way, the command:

StringTools[HasControlCharacter](str);

give false.  OUF!

Thank you both!

It's not working!  I forgot to tell you that this was an extract of a SINGLE line containing 2024 character.  Here how it apprears in Maple after the readdata:

 It look to me as a sequence of part of the data.  This leaded me to think that the problem was the file and the way it was store.  I opened a text editor (Notepad++) and I saw that it was stored with the "Automatic line wrapping".  So I was seeing a lot of line each with the [LF] code at the end.  So I "Select all" and choose "join lines".  And now I am seeing only one line of length 2024.

I re-execute the Maple file and the output is not pretty:

I think that the characters * + / etc cause the problem!

????????????

Any ideas?

Thank you for your support!

Of course, the solution of Preben Alsholm is short and sweet.  But I would like to know why my solution seems so negatif?

I was in a good mood and I wanted to put a little smile to the others collegues.  I can see that you didn't smile.  Sorry.

Since the new MaplePrimes, I am not receiving anymore the maplethread like before.  Is this normal?  Am I missing something?

Thanks in advance,
