Length limits for iHub names

iHub names, such as file and folder names, must not exceed the character string lengths listed in Table 1‑2. These character string length limits apply to the number of Unicode characters. For certain languages, such as Japanese and Thai, the length limit is expressed in terms of the number of code points used to compose Unicode characters. One Japanese character, for example, can comprise up to 4 code points. All code points used count toward the limit. For example, using more than 250 Japanese characters, consisting of 4 code points each, for the name of a file or folder exceeds the 1000 character string limit.
