Code Page Conversion Errors

Code Page Conversion Errors

If it is not possible to convert a character from one code page to another, ICU replaces the character with the substitution value for the current code page by default. Typically, this substitution value is a hexadecimal value, such as x'1A' or x'3F'.
The following situations can prevent character conversion:
  • The character is not valid for the source code page. This situation can be caused by describing the data in the wrong code page.
  • The character is valid in the source code page, but no equivalent character exists in the target code page. This situation is common if converting from multibyte characters to a single-byte target code page.
PowerExchange aborts when connecting to databases or describing tables if a code page conversion error occurs during initialization. PowerExchange uses substitution characters if any column or parameter data does not convert.
The following table summarizes conversion errors by context:
