Why do some platforms count characters differently?
Because each platform measures length its own way. X weighs characters, so a post of emoji or Chinese holds half as many, and a long link costs the same 23 as a short one; how X counts characters explains it in full. Telegram keeps captions to 1,024 characters, so text written for a 4,096-character message overflows once a photo is added. YouTube counts bytes, so a description in accented or non-Latin text reaches its limit sooner.
A caption over the limit is either refused by the platform when it publishes or cut off in the feed. SkedCast counts each version the way its platform does and flags it before the post is scheduled, so nothing fails at publish time.
Do hashtags and mentions count toward the limit?
Yes. Hashtags and @-mentions are part of the caption text on every platform and count toward its length, and some platforms also cap how many a post can carry; see hashtag limits by platform.
