Import of CSV file drops the letter F

Michael Lachance, UM-Dearborn
Posted 10 years ago

Run this; humor me:

alphabet = {"a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"}; TableForm[ list = Table[ StringJoin[IntegerString[k], ToUpperCase[alphabet[[j]]]], {j, Length[alphabet]}, {k, 0, 9}]] Export["digitLetterTest.csv", list, "CSV"] TableForm[Import["digitLetterTest.csv"]]

Shouldn't the standard / default operation be more predictable (don't know if this is the good word), and this drop be active just as an option?

Should Import have "interpretation" on by default? I imagine that the line is blur, and even more on complex file formats, but this case seems too much, and most special because standard letters from the alphabet are included in the list. Interestingly, this seems to have been limited to the english world. I can imagine that all 6500 languages considered, this list could increase significantly (probably that would be good, since it would never caught us by surprise...)

Lower-case c and p, also.

A developer commented,

"c" and "p" are considered "CurrencyTokens" and are skipped by default when used with numerical values. See the Import options for CSV.

See http://reference.wolfram.com/language/ref/format/CSV.html , under Options - Import Options.

Import options:
    "CurrencyTokens"   {{"$", "£", "¥", "€"}, {"c", "¢", "p", "F"}}  currency unts to be skipped when importing numerical values

I submitted a suggestion that a note on this go in the "Possible Issues" section.
