11.11 Filenames encoding ¶

An encoding form parameter can be used to specify the filename encoding encoding=xxx.

• If the form parameter encoding=utf8 appears in the form string, the filename must be encoded in UTF-8.
• If the form parameter encoding=8bits appears in the form string, the filename must be a standard 8bits string.

In the absence of a encoding=xxx form parameter, the encoding is controlled by the GNAT_CODE_PAGE environment variable. And if not set utf8 is assumed.

`CP_ACP'

The current system Windows ANSI code page.

`CP_UTF8'

UTF-8 encoding

This encoding form parameter is only supported on the Windows platform. On the other Operating Systems the run-time is supporting UTF-8 natively.
