Suzhou numerals (蘇州碼子; also 花碼) are Chinese decimal numerals:



0 〇
1 〡 一
2 〢 二
3 〣 三
4 〤
5 〥
6 〦
7 〧
8 〨
9 〩


They pretty much work like Arabic numerals, except that when there are consecutive digits belonging to the set {1, 2, 3}, the digits alternate between vertical stroke notation {〡,〢,〣} and horizontal stroke notation {一,二,三} to avoid ambiguity. The first digit of such a consecutive group is always written with vertical stroke notation.



The task is to convert a positive integer into Suzhou numerals.

                All octal escapes can be replaced by the equivalent single-byte characters (and are counted as one byte each), but used for readability and because otherwise it breaks TIO and SE with invalid UTF-8.



                import StdEnv
                u=mapc={'343','200',c}

                An encoding-unaware compiler is both a blessing and a curse.

                                                  If this is an answer to a challenge…




                                                  • …Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.


                                                  • …Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one.
                                                    Explanations of your answer make it more interesting to read and are very much encouraged.


                                                  • …Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.



                                                  More generally…




                                                  • …Please make sure to answer the question and provide sufficient detail.


                                                  • …Avoid asking for help, clarification or responding to other answers (use comments instead).
