Displaying Characters in ttIsql
The ability of ttIsql to display characters depends on the native
operating system locale settings of the terminal on which you are using
ttIsql.
The ttIsql utility supports the character sets listed in Supported Character
Sets in the Oracle TimesTen In-Memory Database
Reference.
To override the locale-based output format, use the ncharencoding option or the -N option. The valid values for these options are LOCALE (the default) and ASCII. If you choose ASCII and ttIsql encounters a Unicode character, it displays it in escaped format.
You do not need to have an active connection to change the output method.
