+  The following information is being submitted to the standards working group as
+  a proposed resolution to a defect report and is not yet part of ISO 29500-1.
+  ...
+  For each Unicode character in DrawingML text, the font face can be any of four
+  font “slots”: latin (§21.1.2.3.7), cs (§21.1.2.3.1), ea (§21.1.2.3.3), or sym
+  (§21.1.2.3.10), as specified in the following table. For all ranges not
+  explicitly called out below, the ea font shall be used.
+
+  U+0000–U+007F Use latin font
+  U+0080–U+00A6 Use latin font
+  U+00A9–U+00AF Use latin font

+  U+2010–U+2029 Use latin font Except, for the quote characters in the range
+    2018 – 201E, use ea font if the text has one of the following language
+    identifiers: ii-CN, ja-JP, ko-KR, zh-CN, zh-HK, zh-MO, zh-SG, zh-TW.
+  U+202A–U+202F Use cs font
