I need to create a db record with a column with this value
query = "booster pro 12\24 v"
but this is what stored into db column.
"booster pro 12\u0014 v"
if I try with single-quoted I get
'booster pro 12\24 v' -> "booster pro 12\\24 v"
but If I use this, I got the correct string printed.
puts 'booster 12\24 v' -> booster 12\24 v
If I try with single-quoted I get
'booster pro 12\24 v' -> "booster pro 12\\24 v"
This is correct. You've already got the right answer.
A backslash is an escape character. When displaying escape characters in a double-quoted string, you must escape them with a backslash. That means a literal backslash is represented by two backslashes.
Two literal backslashes would be represented by four backslashes, in a double-quoted string.
Or for example, consider:
"\n""\\n"This behaviour is not specific to ruby.
