* Parser for files that are similar to UnicodeData.txt:
* This function opens the file and reads it line by line. It skips empty lines
* and comment lines that start with a '#'.
* All other lines are separated into fields with one delimiter character
* (semicolon for Unicode Properties files) between two fields. The last field in
* a line does not need to be terminated with a delimiter.
* For each line, after segmenting it, a line function is called.
* It gets passed the array of field start and limit pointers that is
* passed into this parser and filled by it for each line.
* For each field i of the line, the start pointer in fields[i][0]
* points to the beginning of the field, while the limit pointer in fields[i][1]
* points behind the field, i.e., to the delimiter or the line end.
* The context parameter of the line function is
* the same as the one for the parse function.
* The line function may modify the contents of the fields including the
* limit characters.
* If the file cannot be opened, or there is a parsing error or a field function
* sets *pErrorCode, then the parser returns with *pErrorCode set to an error code.
