Function 

Description 

vm_chset_ascii_to_ucs2 

Converts the ASCII string to a UCS-2 string. The caller should ensure that the size of the destination buffer is large enough to contain the resulting string. If not, the conversion will only convert a part of the source string up to the size of the destination buffer. In other words, the resulting string is a truncated string up to the size of the destination buffer. 

vm_chset_convert 

Converts a string between 2 character sets, and add the corresponding terminate character to the destination string. The caller should ensure that the size of the destination buffer is large enough to contain the resulting string. If not, the conversion will only convert a part of the source string up to the size of the destination buffer. In other words, the resulting string is a truncated string up to the size of the destination buffer. 

vm_chset_ucs2_to_ascii 

Converts the UCS-2 string to an ASCII string. The caller should ensure that the size of the destination buffer is large enough to contain the resulting string. If not, the conversion will only convert a part of the source string up to the size of the destination buffer. In other words, the resulting string is a truncated string up to the size of the destination buffer.
