In Cupertino I have seen the minimum wage which is actually $8/hour for the part time job like a cacher in the store. The the rent average is $2,000 for one bedroom apartment there. It's totally unfair to low income people. They sacrifice the time to stay with their family and have to work even weekend for bills.
It does not solve the problem. Here is the points which I think.
1. Control characters are not supported in the almost of text editors.
2. Control characters are not human friendly.
3. The text may contain control characters in the field value.
In any formats, we cannot avoid the escape characters, so even I think CSV/TSV format is reasonable.
