Getting this error while trying to upload my paper to the Springer journal.

But it builds fine on my system.

Any help?

U+2061 is FUNCTION APPLICATION that is an invisible zero width character intended to distinguish concatenation meaning function application from concatenation meaning multiplication,. You should be able to simply delete it.

If deleting it is hard then declare it to do nothing add this to the document preamble

\DeclareUnicodeCharacter{2061}{}

on line 136 of your source you have

  U+005c REVERSE SOLIDUS     &bsol; \backslash \textbackslash
  U+006f LATIN SMALL LETTER O     o
  U+0077 LATIN SMALL LETTER W     w
  U+0061 LATIN SMALL LETTER A     a
  U+2061 FUNCTION APPLICATION 
  U+0028 LEFT PARENTHESIS     &lpar; \lparen (
  U+0045 LATIN CAPITAL LETTER E     E

So if you delete everything form the ( back to \owa and then retype the \owa ( without the invisible U+2061 character before the ( then it should be fine.

Note this is unrelated to using mactex or linux etc, you may have U+2061 defined in a package in one place and not the other, it is not defined by default.

If you want to declare it rather than remove it just use

\DeclareUnicodeCharacte{2061}{}

which declares it and makes it do nothing.

to more easily find it add

\DeclareUnicodeCharacter{262F}{YIN YANG HERE!!!!!}

to your preamble, and search the output for that text. If you want it to display then find a yinyang.pdf image and do something like

\DeclareUnicodeCharacter{262F}{\includegraphics[height=1ex]{yinyang}}
