how to support utf-8 character in yaml file?

[jjcizi]

First, your package is great!
But, your package can not support utf-8 character in yaml file. It means a lot of people cant not use their home language to show results.
Can you fix this? Please.
Or tell me how to solve this problem.

Not sure why you believe it doesn't work. Using the the online app at https://ipub.com/dev-corner/apps/ahp/ the following works perfectly fine:

Version: 2.0
Alternatives: &alternatives
  Beach:
    cost: 10000
  Montañas:
    cost: 5000
Goal:
  name: Vacation
  decision-makers:
    #optional node, needed only if not all decision-makers have equal voting power
    - Däd: 0.4
    - Mom: 2/5
    - Kid: 0.2
  preferences:
    Däd:
      pairwise:
      - [Costs, Fön, 4]
      - [Costs, Spa, 9]
      - [Fön, Spa, 4]
    Mom:
      pairwise:
      - [Costs, Fön, 1/4]
      - [Costs, Spa, 1/9]
      - [Fön, Spa, 1/5]
    Kid:
      pairwise:
      - [Costs, Fön, 1/9]
      - [Costs, Spa, 1]
      - [Fön, Spa, 9]
  children:
    Costs:
      preferences:
        Däd:
          pairwiseFunction: 
            function(a1, a2) min(9, max(1/9, a2$cost/a1$cost))
        Mom:
          scoreFunction:
            function(a) 1/a$cost
        Kid:
          priority:
            - Beach: 1/2
            - Montañas: 0.5
      children: *alternatives
    Fön:
      preferences:
        Däd:
          pairwise:
            - [Beach, Montañas, 1/6]
        Mom:
          pairwise:
            - [Beach, Montañas, 2]
        Kid:
        # Often, entering pairwise preferences is lengthy, especially if you
        # have multiple alternatives. Instead, you can enter scores, i.e. rate
        # each alternative on a scale. The scale can be chosen freely. The 
        # priorities are derived as score / sum(scores)
          score:
            - Beach: 5
            - Montañas: 0
      children: *alternatives
    Spa:
      preferences:
        Däd:
          pairwise:
            - [Beach, Montañas, 2]
        Mom:
          pairwise:
            - [Beach, Montañas, 6]
        Kid:
          pairwise:
            - [Beach, Montañas, 1/2]
      children: *alternatives

Can you pls provide a reproducible example of what is not working for you? Ideally as a gist. Thx!

Thx for reply. but when I use the yaml code which you give above, still garbled.
Däd, Montañas,etc. changed to garbled.
But it is indeed normal , works, on the the online app at https://ipub.com/dev-corner/apps/ahp/.
Why?

[jjcizi]

solved.

x <- readLines("file.yml")
x <- iconv(x,'UTF-8','UTF-8')
writeLines(x,"file.yml")

use icove() to change file to utf-8 ,then works.

thank you very much.
