Why Force.Com Migration Tool Does NOT deploy CustomMetadata Records?

There is some invisible character in documentation between small 'm' and capitalised 'M' in CustomMetadata and in the closing </members> tag (&​#8203; Unicode Character 'ZERO WIDTH SPACE' (U+200B) http://www.fileformat.info/info/unicode/char/200b/index.htm ), that is why this code

<types>
    <members>*</​members>
    <name>Custom​Metadata</name>
</types>

doesn't work while this would work

<types>
    <members>*</members>
    <name>CustomMetadata</name>
</types>
