+ * mbcheck.c - writes the location of each string in a single char * but
+ * ignores single byte characters to see ONLY emojis. By write location and see
+ * where only emojis are it means warn about it, not print it out itself.
+ *
+ * This way I can check if the ASCII only data file has any emojis (or other
+ * multibyte characters) by accident. This is why it reads from the ASCII only
+ * data source file by default, but it can be used on data.src too with -i
+ * data.src to see which strings have emojis.
+ *
+ * It reads one 'string' at a time; it does not read in the whole file at once.
+ * option it allows for another file.
