Note: This form of conversion may eventually be removed from the language.
The <a href="/pkg/cmd/vet"><code>go vet</code></a> tool flags certain
integer-to-string conversions as potential errors.
Library functions such as
<a href="/pkg/unicode/utf8#AppendRune"><code>utf8.AppendRune</code></a> or
<a href="/pkg/unicode/utf8#EncodeRune"><code>utf8.EncodeRune</code></a>
should be used instead.
