Re: [naviserver-devel] ns_returnfile return original file name

[Gustaf N. <ne...@wu...>]

Dear Oscar,

In principle, you are right concerning the encoding. A few comments:

- on most browsers, also utf-8 filenames are accepted,
    but the use of UTF-8 in the header fields is not recommended.

- For the percent encoding, one should use "ns_urlencode -path", e.g.,

          ns_urlencode -part path {£ and € rates}

    since the "ns_urlencode" without parameters (as in your example) 
uses a special rule for the space character.

One should actually provide an API along the lines of:

     ns_header_field_parameter -charset /charset/ -language /language/ 
name string

to ease its usage. ... maybe something for the next release...

All the best

PS: Minor nitpick: RFC 5987 was obsoleted by RFC 8187
