-C COL issue

[yudalosw]

Target is MySQL >= 5.0.0 BTU exploitable.
Fetching with --dump after -T table_name works fine.
Fetching only specific columns from table_name result in a fail.
I am using option -C column1,column2,column3,column4,column5,column6,column7,column8 --dump

[INFO] fetching entries of column(s) 'column1, column2, column3, column4, column5, column6'

Notice the accents U+60 around column1?
If I remove column1 from the specified columns to be dumped, there is no more accents at any of the columns names.
However it still fails with the same error:

[WARNING] something went wrong with full UNION technique (could be because of limitation on retrieved number of entries). Falling back to partial UNION technique
[WARNING] the SQL query provided does not return any output

1. accents are a special escaping mechanism used in MySQL when the identifier looks like a reserved-keyword. In regular case, it should not cause problems - even more, there are more benefits of using it than disabling it. Please don't reply with "but my column doesn't need escaping" - there is a generic list of keywords embedded inside the sqlmap. IT SHOULD not be a problem in general case, even escaping of all the columns/identifiers
2. Tried to reproduce, had no problems - even when forced the usage of those "accents"
3. With latest revision/commit you should be able to prevent that "escaping" with the usage of --no-escape
