To Kanji or Not To Kanji for うまく・上手く?


I picked up the following phrase to say "I hope you are well":

> うまくいきますように!

Looking this up in a dictionary, it seems it could become:

> 上手く行きますように!

Is this correct, or is it better to leave out the Kanji-fication?




A rough¹ count of the results in the Balanced Corpus of Contemporary Written
Japanese (少納言) gives the following numbers

[code]

    上手くいく   274     8.2%  
    上手く行く    93     2.8%  
    うまくいく  2742    82.4%  
    うまく行く   220     6.6%
    
[/code]

leaving out rare (<1%) kanjifications such as 旨く行く.

¹ I checked い・く and 行・く for the following conjugations: ～く、～か、～っ、～き, but
didn't check the individual results for false positives.

These numbers clearly suggest **Not To Kanji** for うまくいく (as a general rule —
writing by numbers is just like painting by numbers, i.e. not the height of
the art).

うまい itself has [slightly different
numbers](http://nlb.ninjal.ac.jp/headword/AJ.00016/), but still suggesting Not
To Kanji:

    うまい    11153    79%
    上手い     1837    13%
    旨い        665     5%
    巧い        238     2%
    美い        167     1%
    ウマい       58     0%
