Hi All,
Could you please tell me how can we remove UTF-16 BE ENCODING special characters from string using ESQL.
Thanks in advance. |

Two important questions:
- why do you need to remove the special characters?
- When removing these characters, why is the encoding ( UTF16-BE ) important? |

So do you:
a) want to remove the encoding information so that no-one can ever read the string again
b) want to remove the encoding information because whatever's reading the string doesn't use UTF-16 BE?
If it's the former, just blank out the string. If it's the latter (as I suspect), you're much better off changing the code page of the string to whatever the consuming application needs because that's probably going to work and just stripping off the encoding isn't.

It didn't occur to me that the OP might be asking about the Byte Order Mark at the beginning of the string. I thought the question was about 'special characters' in general...which just confirms my dislike of the term 'special characters'.
@Ashok Kumar: Please clarify. Do you want to
a) remove the two bytes of the UTF-16 BOM from the beginning of a string
or
b) remove non-ASCII characters from a string?
Either way, please also explain why you need to do this - our advice may change depending on your requirements. |
