# [Uiua](https://uiua.org/), 10 bytes (SBCS)

Counts all digit occurrences and checks the count array is all-equal (for which there is no short idiom in Uiua yet except for that deduplicate-length-equal-to-one and similar gymnastics).

```uiua
=1⧻◴⊕⧻⊸⊛°⋕
```

### Explanation

```uiua
=1⧻◴⊕⧻⊸⊛°⋕    112233        example input
          °⋕    "112233"      unparse: convert to character array
       ⊸⊛      [0 0 1 1 2 2] "112233" push unique index per element,
                                       keep argument on stack
    ⊕⧻         [2 2 2]       determine per-group length: count array
   ◴            [2]           deduplicate count array
  ⧻             1             determine its length
=1              1             equal to 1?
