| Name | Type | Description |
| bUseUnicode | AT_PDF_BOOL | If TRUE, translate the string to Unicode; otherwise use PDFDocEncoding. |
| szInHostStr | LPCSTR | Pointer to the string to translate (may point to the same memory as szOutPDFStr, allowing strings to translate in place). |
| nInHostStrSize | LONG | Number of bytes in szOutPDFStr. |
| szOutPDFStr | LPSTR | Pointer to the translated string (may point to the same memory as szInHostStr). |
| nOutPDFStrSize | LONG | The length of the szOutPDFStr buffer, in bytes. |
| lpnOutPDFStrBytes | LPLONG | Number of bytes in the translated string szOutPDFStr. |

This function does not process image pixels.
This function is useful when using text that must be in PDFDocEncoding or Unicode, such as text in a text annotation, bookmark, or article title.
A character that cannot be converted to the destination encoding is replaced with a space.
For example, it converts \n to a space character (\r is present in PDFDocEncoding and is left unchanged).
Host encoding is a platform-dependent encoding for the host machine. For non-UNIX Roman systems, it is MacRomanEncoding in Mac OS and WinAnsiEncoding in Windows. In UNIX (except HP-UX) Roman systems, it is ISO8859-1 (ISO Latin-1); for HP-UX, it is HP-ROMAN8. See Appendix D in the PDF Reference for descriptions of MacRomanEncoding, WinAnsiEncoding, and PDFDocEncoding.
For non-Roman systems, the host encoding may be a variety of encodings, which are defined by a CMap (character map). See Section 5.6.4 in the PDF Reference for a list of predefined CMaps.
Use IG_PDF_get_host_encoding to determine if a system's host encoding is Roman or not.
