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?

question
kanji orthography hiragana
To Kanji or Not To Kanji for うまく・上手く?
Personally I don't think it makes a huge difference to use kanji or not for
short phrases like that, but its good to use kanji if you have a massive wall
of text because it can make it easier to digest and you can get the meaning
quicker than by parsing every hiragana character one by one into words

It depends on your audience.

For anything longer than a simple phrase, the only place you'll see all
hiragana is in children's books. But newspapers use more kanji than most
people sending IMs to each other. Even then it can depend on the person. And
not just education level, but individual idiosyncrasies.

Really, it comes down to experience. You send and receive enough messages
until you get a sense for what words are not written in kanji even though they
exist, what words are _almost_ always written in kanji, and what is considered
a good balance between kanji and hiragana when a lot of the words could go
either way (think daily conversation level).

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

```

    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%
    
```

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%
