Missing source links for certain combinations of text accents and characters

[ktraunmueller]

Some combinations of accent marks with characters fail to produce proper source links:

Specifically,

• ring over: \r{a} works, \r{o} not
• breve \u{o} also doesn't work

Update using version 1.22 and the example document below:

Cases:

• ring over o \r{o}: turns out there is no such character in the T1 encoding, TeX seems to be substituting an o with an overset ring anyway, but we don't need to handle this degenerate case.
• breve over o \u{o}: again, there is no such character in the T1 encoding
• Ø (Oslash) {\O} and ø (oslash) {\o} are valid characters in T1 → created #581
• $ → created #582
