<p>One part of the analysis is that it's a glyph variant that's
font-specific. So, you will need rich text and styling to identify
a specific font that will supply that glyph. This conclusion is
further supported whenever such a difference is specific to a
certain document, or series of publications, and there's no
contrasting use. <br>
</p>
<p>The next part of the analysis is to determine the appropriate
plain text back-storage (and with it, the plain text fallback) for
this variant. There has been a suggestion that the proper plain
text should be o + combining e above. That would preserve the
stylistic choice of using the letter "e" shape instead of the
double dots to represent umlaut.</p>
<p>While German users can be expected to "immediately understand" an
oͤ for an ö, there's a serious argument to be made that on the
level of <b>content</b>, the intention is to represent an ö,
therefore, that's what the plain text should contain, and the
glyph variation is relative to that, and not a variant of oͤ. The
latter would be appropriate for situations where the use of the
small e glyph over the double dots is contrastive, or represents
something other than styling.</p>
<p>Otherwise, it would just be likely to impede processes such as
search to use oͤ in the plain-text back storage.</p>
<p>If someone wrote a Swedish text with an o enclosing an e, the
analysis might come to the conclusion that readers would e
surprised to expect it to represent an ö. Therefore, oͤ as the
plain text storage in that case might indeed be better. (Unless
it's a quotation from the German).<br>
</p>
<p>This leads to the third step of the analysis: the font's glyph
variation should be language specific, unless the designer intends
the font only to be useful for German.<br>
