# ICU - Unicode Insertion Character

With this session parameter, you specify the character string to be inserted in the column immediately preceding the value of a field output with a `DISPLAY` statement. The width of the output column is enlarged accordingly.

Possible settings | any character | Character string to be inserted. You can specify a string of one to ten characters. Note Insertion characters may optionally be specified within apostrophes, in which case any characters can be specified. Any character string specified which contains a closing parenthesis or a quotation mark must be enclosed within apostrophes. A blank in a character string not enclosed within apostrophes is represented by a circumflex (^).
Default setting | none |
Specification within session | yes |
Applicable statements | `FORMAT` | Parameter may be specified dynamically with the `FORMAT` statement.
`DISPLAY` | Parameter may be specified at statement level and/or at element level.
Applicable command | none |

Notes:

1. The session parameter `ICU` is identical to the session parameter `IC`. The difference is that the insertion characters are always stored in Unicode format. This allows you to specify insertion characters with mixed characters from different code pages, and assures that always the correct character is displayed independent of the installed system code page.
2. For numeric values, the insertion characters will be placed before the first significant digit printed.
3. The parameters `ICU` and `LCU` are mutually exclusive.
