Bad URI when a file name has brackets

[DmitryBarskov]

When I try to add a watermark to a file with [ or ] in its name, I get #<URI::InvalidURIError: bad URI (is not URI?): "https://v2.convertapi.com/d/p2bempn0sjua63w36zyxjr2d2weq7o34/[dev]+sample.pdf">

ConvertApi.convert(
  "watermark-overlay",
  {
    File: "./[dev] sample.pdf",
    OverlayFile: ConvertApi::UploadIO.new(File.open("some-other.pdf")),
    Scale: "75",
    Opacity: "30",
    Style: "stamp"
  },
  from_format: "pdf"
).file.save("./sample.watermarked.pdf")
#<URI::InvalidURIError: bad URI (is not URI?): "https://v2.convertapi.com/d/p2bempn0sjua63w36zyxjr2d2weq7o34/[dev]+sample.pdf">

If I try to do it without saving, it will be OK, but the URI provided is not a valid URI nor URL:

ConvertApi.convert(
  "watermark-overlay",
  {
    File: "./[dev] sample.pdf",
    OverlayFile: ConvertApi::UploadIO.new(File.open(SaasAppSettings.instance.watermark_file_path)),
    Scale: "75",
    Opacity: "30",
    Style: "stamp"
  },
  from_format: "pdf"
).file

#<ConvertApi::ResultFile:0x0000ffff94106a28
# @info=
#  {"FileName"=>"[dev] sample.pdf",
#   "FileExt"=>"pdf",
#   "FileSize"=>121463,
#   "FileId"=>"y0xnqdx161tcmbghnf0x3yjniih0ckek",
#   "Url"=>"https://v2.convertapi.com/d/y0xnqdx161tcmbghnf0x3yjniih0ckek/[dev]%20sample.pdf"}> <= invalid!
# but it should be 'https://v2.convertapi.com/d/f82j2d0chmxv4xqqa45s3kql613al2aj/%5Bdev%5D+sample.pdf'

So I think it should be fixed on the server. The workaround I found is to patch the ConvertApi::ResultFile:

require "addressable/uri"

module ConvertApi
  class ResultFile
    def url
      Addressable::URI.parse(info["Url"]).normalize.to_s
    end
  end
end

which requires this gem https://github.com/sporkmonger/addressable.

Ruby version 3.2.9 (but I think it does not depend)
Library version 2.0.0 or 3.0.0 (tried on both, but I think it does not depend on library version, since the bug is in the API)
