Dear list,
https://wiki.contextgarden.net/Greek#Monotonic_and_Acute_Accent includes
two samples that should display the difference betweeen the monotonic
accent and the polytonic acute accent (which generate two different
characters for each such accented vowel).
Excluding other implications, these are two different characters. In
some fonts each pair of different characters for each accented letter
lead to the same glyph, in other fonts those glyphs are different.
This sample shows the difference (there should display two slightly
different accents [unless there is some character normalization on the
way]):
\definefontfamily[mainface][rm][EBGaramond]
\setupbodyfont[mainface, 500pt]
\definecolor [tred] [r=1,t=.5,a=1]
\definecolor [tblue] [b=1,t=.25,a=1]
\starttext
\startTEXpage[offset=1ex]
\startoverlay
{\color[tred]{Ά}}
{\color[tblue]{Ά}}
\stopoverlay
\stopTEXpage
\stoptext
The problem that I have is tricky. Thanks to character normalization (at
least in Firefox), searching for "á" will also find "a" (unless “Match
diacritics” is enabled).
I’m afraid the wiki is performing some character normalization, which
renders samples in
https://wiki.contextgarden.net/Greek#Monotonic_and_Acute_Accent useless.
Searching for "Ά" in https://wiki.contextgarden.net/Greek should give
not more than 4 matches (not case-sensitive and with “Match diacritics”
[or similar filter for your browser] enabled). I‘m afraid I get none.
While editing the article searching for "Ά" (case-insensitive and not
normalizing characters), gave me 4 matches, but only in the source (no
ocurrence was found in the preview).
Once changes are saved, "Ά" occurrences dissapear (since they seem to be
normalized).
Sure, they may be a workaround to type codepoints instead of characters
(such as with \utfchar{0x1fbb}, but wouln’t it be possible to disable
that character normalization in the wiki?
Many thanks for your help,
Pablo
