the acute accent will be in your bibliography you can use the answers in the duplicate question to make them show as ******** in the output then re-type them as an accented characetr or using the latex \' command.

you have not given much information but looks like it is in your bibliography from what you have shown so far

@DavidCarlisle Thanks. I found is one my of chapter bibliography. I presume is because I am using special character e

You can use é or \'{e} what you can not use is a normal e followed by the Unicode combining acute U+0301

@DavidCarlisle Thanks. I added \DeclareUnicodeCharacter{0301}{*************************************} and it work very well. I did not change anything in my bibliography

That is only a debugging device it will literally insert ************** into your PDF document so that you can see where to change the bibliography (I usually use FIX ME HERE!!! rather than ***********)
