​In zh_CN of 12.0 CE, the record g/m/t of uom miss translation item , and the translation item of record "fl oz"  is incorrect.
So I make a po file to fix it.

#. module: uom

#: model:uom.uom,name:uom.product_uom_floz

msgid "fl oz"

msgstr "液盎司"

#. module: uom

#: model:uom.uom,name:uom.product_uom_meter

msgid "m"

msgstr "米"

#. module: uom

#: model:uom.uom,name:uom.product_uom_ton

msgid "t"

msgstr "吨"

#. module: uom

#: model:uom.uom,name:uom.product_uom_gram

msgid "g"

msgstr "克"

When I import this po file with --i18n-overwrite option, the reocrd g/m/t of uom is show translate name, but the translation of recode "fl oz" is not overwrite.

If I fix translate item for "fl oz" in uom module's i18n po file, this issue can be fix.

How to overwrite the translate terms of  uom.uom records without modify offical source?
