plsql - What encoding is used when calling an Oracle PL/SQL procedure -

-

on coldfusion page call pl/sql procedure. html form encoded using utf-8, oracle db has encoding we8iso8859p1. kind of conversion happens in case of i_value below?

i'm interested in happens ms word left quote (which encoded in utf-8 e28098). when decode i_value in pl/sql becomes 18(hex). considering u+2018 makes sense, still wonder why 20 swallowed.

<cfstoredproc procedure = "my_schema.lib.write_field" datasource="#datasource#">         <cfprocparam cfsqltype="cf_sql_varchar" variable="i_name"   value="remark"  type="in">         <cfprocparam cfsqltype="cf_sql_varchar" variable="i_value" value="#form.remark#" type="in"> </cfstoredproc>

coldfusion java based guess string variables encoded using utf-16.

when going utf-16(2 byte encoding) 1 byte encoding(e.g. we8iso8859p1) case in example, msb ignored , lsb considered.

this explain observed behavior: noticed of bytes seem swallowed when sent db, e.g. left single quotation mark (0x2018 in utf-16) becomes 0x18 in db.
