telugu-glyph

Your mission

Count how many glyphs a piece of text draws once the combining marks are attached.

today's brief

February 2018. One Telugu character, dropped into a message, takes iOS down: the app dies on receipt and dies again every time the thread is reopened. Any app that tried to render it was gone. The character was a consonant joined to a vowel sign that the layout engine could not build into a single glyph. Count the glyphs before you draw them.

Your checklist

For your own tracking. Tests grade your code.

s is a null-terminated string of letters only.
A lowercase letter is a base character and draws a glyph of its own.
An uppercase letter is a combining mark: it is drawn on top of whatever comes before it, so it adds no glyph.
A mark with nothing before it has nothing to attach to and draws on its own.
Return the number of glyphs drawn.
