C++のコンパイルがうまくいきません

C++ のコンパイルでエラーが出てはまっています。

環境はmacOSです。

コンピュータ将棋のアルゴリズムというサイトでソースコードが紹介されていたのでそれを動かそうとしています。
http://homepage1.nifty.com/Ike/ComShogi/02.html
のchapter02フォルダのKomaMoves.cppをコンパイルしようとしています。

まず出たエラーが下記です。

コマンドは% g++ -o komaMoves KomaMoves.cpp

KomaMoves.cpp:206:67: error: source file is not valid UTF-8
  ...<8B><E0>","<94>n","<97><B4>",
     ^
KomaMoves.cpp:206:68: error: source file is not valid UTF-8
  ...<E0>","<94>n","<97><B4>",
     ^
KomaMoves.cpp:206:72: error: source file is not valid UTF-8
  ...<94>n","<97><B4>",
     ^
KomaMoves.cpp:206:77: error: source file is not valid UTF-8
  ...<97><B4>",

日本語が書かれている箇所があったのでそこに原因があると思いそこをとりあえず削除して実行できるか確認したところ、続いて下記のエラーが出ました。

% g++ -o komaMoves KomaMoves.cpp
Undefined symbols for architecture x86_64:
  "_main", referenced from:
     implicit entry/start for main executable
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

どうすればコンパイルできるかご教示いただけるとありがたいです。
