可以通过用户上传图片，生成头像？还是只能通过字来生成头像
偏移的规则是怎么计算的呢？
头像显示不了文字，发现是fonts文件夹中的字体文件坏掉了 ，我把Carbon-Forum中相应的字体文件复制过来覆盖就可以了
css控制已经有圆角了
代码中看到已经支持了Psr-4，但在实际使用时，通过composer安装后的包里还是不支持Psr-4。composer update lincanbin/material-design-avatars--prefer-source 也不行，能否解决一下？

$this->Char = strtoupper(mb_substr($Char, 0, 1, "UTF-8"));这块的strtoupper是起到什么作用的呢？
Md\MDAvatars Object
(
[Char] => Ʊ�
[AvatarSize] => 512
[Padding] => 60
[Avatar] => Resource id #5
[FontFile] => /Users/kslr/Develop/Material-Design-Avatars/src/fonts/SourceHanSansCN-Normal.ttf

[AsianFont] => /Users/kslr/Develop/Material-Design-Avatars/src/fonts/SourceHanSansCN-Normal.ttf
[EnableAsianChar] => 1
)移除 strtoupper
➜ Material-Design-Avatars git:(master) ✗ php test.php

)发现文档中有一句“
注意 “字母” 与当前所在区域有关。例如，在默认的 “C” 区域，字符 umlaut-a（ä）就不会被转换。”

是否和这个有关系呢？
