+<function>FcStrCopyFilename</function> constructs an absolute pathname from
+<parameter>s</parameter>. It converts any leading '~' characters in
+to the value of the HOME environment variable, and any relative paths are
+converted to absolute paths using the current working directory. Sequences
+of '/' characters are converted to a single '/', and names containing the
+current directory '.' or parent directory '..' are correctly reconstructed.
+Returns NULL if '~' is the leading character and HOME is unset or disabled
+(see <function>FcConfigEnableHome</function>).
