私は同じコマンドを試して、同じ結果を得ました。
$ printf "\u2318" | convert -size 100x100 label:@- \
-font unifont-Medium command.png
ただし、文字Gのユニコードに変更しても問題はありません。
$ printf "\u0047" | convert -size 100x100 label:@- \
-font unifont-Medium command.png
私はこの質問をImageMagick Discourseサイトに投稿して、これが発生している理由を確認します。これを行う方法または続行する方法がわからない場合は、私がお手伝いします。
変換のデバッグ
-debug annotate
スイッチを追加して、現在の状況を確認できconvert
ます。
例
$ printf "\u2318" | convert -size 100x100 label:@- -font unifont-Medium -pointsize 40 -debug annotate command.png

アップデート#1-さらにデバッグ
この問題は私を苛立たせたので、私は最終的にそれを理解したと思います。問題は、フォントの選択であり、その特定のグリフを表示できないことです。
まず、このコマンドを使用して、で使用できるフォントを確認できますconvert
。それでは、始めましょう。
$ convert -list font | head -8
Path: /etc/ImageMagick/type-ghostscript.xml
Font: AvantGarde-Book
family: AvantGarde
style: Normal
stretch: Normal
weight: 400
glyphs: /usr/share/fonts/default/Type1/a010013l.pfb
...
上記はサンプルを示しています。すべてのフォントには上記と同様の行があります。ちなみに、このコマンドを実行すると、数百のフォントがあることがわかります。
$ convert -list font | grep Font | wc -l
262
次に、\u2318
すべてのフォントを使用して、文字をエンコードするタスクを実行します。これは複雑に聞こえますが、Bashを介していくつかのよく考えられた1つのライナーがあるため、かなり簡単です。
$ for i in $(convert -list font | grep Font | awk '{print $2}'); \
do convert -font $i -pointsize 36 label:⌘ ${i}.gif;done
このスニペットは、forループを使用して各フォントを実行し、convert
コマンドの変更されたバージョンを実行します。
次に、結果を確認します。フォントの多くはこの特定のグリフを表示できませんでしたが、いくつかは表示できました。これは、必ずしもImageMagickのバグではなく、フォント自体の制限であることを示しているようです。これが、このグリフを表示できるフォントのリストです。
- DejaVu-Sans-Bold
- DejaVu-Sans-Bold-Oblique
- DejaVu-Sans-Book
- DejaVu-Sans-Condensed-Bold

結果の約260 .gif
ファイル全体を視覚的に調べ、どのファイルが機能し、どのファイルが機能しなかったかを確認しました。以下は、正常に機能するもののうちのいくつかのサンプルです。
