No it is not. As also indicated in the tips¬es, Turkish differentiates between a present simple (geniş zaman) and a present continuous (şimdiki zaman) tense.
Sometimes when an "r" comes at the end of a word, it takes on a slight "sh" sound. I noticed it when I first went to Turkey and was very confused too. Some words have a more noticeable emphasis than others. It's very strong when some people say "hayır" (no).
i = as the "i" in "sit"
ç = as the "ch" in "church" (if you were writing the pronunciation of this using Turkish letters, it would be "çörç")
e = as the "e" in "get"
r = as the "r" in "car"
So, içer is pronounced i-çer, which in English would be ih-cherr. (perhaps not the easiest to transcribe. have a look at the google translate link below for an audio clip)
